| Influenza, COVID-19, and respiratory syncytial virus (RSV) are three viral respiratory infections that cause most respiratory-related hospitalizations and deaths in our communities. Influenza and RSV cause seasonal epidemics with timing that varies year to year; COVID-19 burden continues to rise and fall with no seasonality. U.S. CDC anticipates that the upcoming fall and winter respiratory disease season will likely have a similar or lower number of combined peak hospitalizations due to COVID-19, influenza, and RSV compared to last season. Nonetheless, with COVID-19, seasonal influenza, and RSV, even an average respiratory season can place substantial strain on the health care system. It is crucial for Maine clinicians to stay up to date with the latest information about prevention, testing, and treatment for these three respiratory infections to reduce the burden of severe disease on our population. |

| The Maine Center for Disease Control and Prevention (Maine CDC) reports 101 pertussis cases between January 1 and October 23, 2024. This surpasses the 76 cases reported throughout all of 2023. Ages ranged from 1 month to 55 years old. Teenagers (13-19 years old) accounted for 43% of cases. Children under 5 years old accounted for 26% of cases.
This increase in cases is not exclusive to Maine. The U.S. Centers for Disease Control and Prevention (U.S. CDC) shared that more than 5 times as many cases had been reported nationally as of October 19, compared to the same time in 2023.
Pertussis is most effectively treated in the first, most mild, stage of illness. It is important to consider pertussis as a possible cause of cough illness, particularly in persons who have had a cough for over one week, or persons who have had exposure to someone with pertussis. To assist in this effort, Maine CDC created a pertussis guide for health care providers so that health care professionals have a resource they can use to build knowledge of pertussis and to help navigate the identification, testing, treatment, and prevention of illness. |

Further information is provided here for Maine facilities and providers. No confirmed cases of MVD related to this outbreak have been reported in the United States or other countries outside of the Republic of Rwanda to date.
Any patients with confirmed or suspected Marburg virus disease must be reported immediately to Maine CDC by phone at 800-821-5821.
All health care facilities (including outpatient clinics, urgent care centers, etc.) should prepare to identify, isolate, and inform key partners when a patient/client presents with signs/symptoms concerning for Marburg virus disease. Information and health care facility readiness assessment tools are available from the U.S. CDC at https://www.cdc.gov/marburg/site.html#hcp and the National Emerging Special Pathogens Training and Education Center (NETEC) at https://netec.org/education-training/.
The Maine CDC can provide guidance regarding how to test for Marburg, malaria, and influenza, and how to transfer a patient to another facility, if appropriate. HETL can perform norovirus, respiratory virus, and malaria testing.
Please note that this health advisory highlights new the U.S. CDC interim recommendations for public health management of U.S.-based healthcare personnel who were present in a healthcare facility in Rwanda in the previous 21 days (released October 3, 2024). These interim recommendations include post-arrival symptom monitoring of health care workers by health departments. They also include exclusion from work duties in a U.S. health care facility until 21 days after their last presence in a health care facility in Rwanda. This applies to all U.S. health care workers who have been present in any health care facility, including outpatient settings or traditional healers, in Rwanda, within the last 21 days and who are returning to the United States.

| Ground-level particle pollution concentrations are expected to reach the 'Unhealthy for Sensitive Groups' (USG) level in the Eastern Interior and Mid-Coast Regions for today and tomorrow according to Air Quality Meteorologists at the Maine Department of Environmental Protection.
Smoke from a fire in Orrington is causing high particle pollution levels at local monitors, one of which was sited by the Maine DEP on Wednesday to measure localized air quality. The winds in the Penobscot River Valley are expected to remain from the south over the next 24 hours. Maine DEP is issuing this air quality alert as authorities anticipate that the fire is expected to burn for at least one more day. While valley locations will be especially susceptible to higher levels of particle pollution, all areas in the vicinity should take precautions.

| Please review this information about an increased risk of Oropouche virus (OROV) infection in the U.S. associated with an increase in global Oropouche activity and key actions clinicians can take to recognize Oropouche, order appropriate testing, ensure timely reporting to public health authorities, and promote prevention measures.
Oropouche virus is an emerging arthropod-borne virus spread by biting midges and mosquitoes. Initial symptoms are non-specific and may resemble chikungunya, dengue, and Zika. Symptoms usually start 3-10 days after a bite from an infected midge or mosquito and resolve after a few days, but 70% experience recurrent symptoms days to weeks after initial illness.
Clinicians should consider OROV infection in symptomatic patients with recent travel to any area with OROV activity. Because dengue co-circulates in many areas with OROV activity, dengue infection should be ruled out before testing for OROV. Testing for OROV, for symptomatic patients meeting the suspect case definition, is available only at U.S. CDC and must be approved by Maine CDC. If approved, samples can be sent to the Maine Health and Environmental Testing Laboratory (HETL). Clinicians can refer to U.S. CDC specimen requirements to determine the proper specimens to submit for testing. A HETL Requisition Form and Human Arbovirus Submission Form are required with all submissions.

| The U.S. Centers for Disease Control and Prevention (U.S. CDC) is issuing this Health Alert Network (HAN) Health Advisory to notify healthcare providers, public health authorities, and the public about current increases in human parvovirus B19 activity in the United States. Parvovirus B19 is a seasonal respiratory virus that is transmitted through respiratory droplets by people with symptomatic or asymptomatic infection. In the first quarter of 2024, public health authorities in 14 European countries observed unusually high numbers of cases of parvovirus B19. In the United States, there is no routine surveillance for parvovirus B19, and it is not a notifiable condition. Recently, U.S. CDC has received reports indicating increased parvovirus B19 activity in the United States. Data include increased test positivity for parvovirus B19 in clinical specimens and pooled plasma from a large commercial laboratory, and reports of clusters of parvovirus B19-associated complications among pregnant people and people with sickle cell disease. The proportion of people with IgM antibodies, an indicator of recent infection, increased among all ages from <3% during 2022-2024 to 10% in June 2024; the greatest increase was observed among children aged 59 years, from 15% during 20222024 to 40% in June 2024. Among plasma donors, the prevalence of pooled samples with parvovirus B19 DNA >104 IU/mL increased from 1.5% in December 2023 to 19.9% in June 2024. |

| Please take a moment to review this information from U.S. CDC on mpox transmission in the Democratic Republic of the Congo (DRC) and neighboring countries that involves monkeypox virus Clade I. No cases of clade I mpox have been reported outside central and eastern Africa at this time.
Information for health care providers on mpox testing, vaccination, treatment, and infection control can be found at https://www.maine.gov/dhhs/mecdc/infectious-disease/epi/zoonotic/monkeypox-providers.shtml. Health care providers who suspect mpox in a person with travel to DRC and neighboring countries should send specimens to Maine's Health and Environmental Testing Laboratory (HETL) for mpox testing. For patients without travel to DRC and neighboring countries, Maine CDC encourages clinicians to use commercial laboratories for mpox testing.
Maine CDC strongly encourages clinicians evaluating persons for mpox to also evaluate and screen for sexually transmitted infections (STIs), including HIV, syphilis, gonorrhea, and chlamydia per the U.S. CDC STI Treatment Guidelines.
Any confirmed case of mpox should be reported to Maine CDC by electronic laboratory report or phone.

| Maine CDC recently confirmed that a mosquito pool (a batch of 1-50 mosquitoes) collected from Orono in Penobscot County tested positive for Jamestown Canyon virus. This is the first local mosquito pool to test positive for any arbovirus this year.
The purpose of this health advisory is to alert clinicians to the potential for human arboviral disease activity in Maine and to consider testing for mosquito-borne arboviruses in patients presenting with unexplained encephalitis, meningitis, or fever (100.4F or 38C) during the summer and fall, particularly among returning travelers.
Eastern Equine Encephalitis virus (EEE), West Nile virus (WNV), and Jamestown Canyon virus (JCV) are serious arboviral infections transmitted by the bite of an infected mosquito. All three viruses are endemic in Maine. Maine reported zero human cases of mosquito-borne arboviral illness in 2023. Although rare, these diseases can have severe and even fatal consequences for those who contract them.

| Hepatitis C infections have risen nationally in recent years, with Maine reporting the highest rate of acute infections in the country in 2020, 2021, and 2022. The rise in hepatitis C infections across the country has been linked to injection drug use and significant gaps in diagnosis, treatment, and prevention.
Universal and risk-based screening is the entry point into the HCV continuum of care and is a crucial and necessary component of any HCV elimination strategy. The U.S. Centers for Disease Control and Prevention (U.S. CDC) recommends universal screening for individuals aged 18 years old and older and periodic risk-based screening for any persons with certain risk factors, screening during each pregnancy and for exposed infants, and confirmatory testing with a hepatitis C virus (HCV) nucleic acid test (NAT). All diagnosed individuals should receive follow-up care and treatment with direct-acting antivirals that can cure over 95% of patients in 8-12 weeks. Treatment is recommended for all infected persons, including persons living with HIV and persons with active substance use.
This health advisory provides a comprehensive overview of recommendations and strategies for increased screening, diagnosis, treatment, and prevention services for persons with or at risk for acquiring hepatitis C.

| Please take a moment to review this health advisory about disrupted access to prescription stimulant medications related to a federal health care fraud indictment against a large telehealth company that provides ADHD treatment. This disruption could impact as many as 30,000 to 50,000 patients across the U.S. Patients with disrupted care or access to prescription stimulant medications are at increased risk for overdose if they obtain counterfeit pills that contain unexpected substances such as fentanyl.
If you become aware of someone in Maine in need of support as a result of this medication access disruption, OPTIONS is here to help. OPTIONS liaisons are available to connect individuals to support resources. For more information, please go to https://knowyouroptions.me/options-liaisons/.
There were at least 29,868 nonfatal drug overdoses in Maine from 2021-2023. These people survived because someone was there to identify the sights and sounds of an overdose and was able to respond and because Naloxone was available for individuals and for law enforcement and emergency medical personnel. Since 2019, Maine has made naloxone available to organizations and community members that wish to have it-on hand in case of an opioid overdose emergency or to distribute to individuals that use opioids as well as their loved ones. The Maine CDC emphasizes the importance of carrying naloxone due to the possible presence of fentanyl in counterfeit pills. For more information, visit https://knowyouroptions.me/get-naloxone/

| After a stretch of relatively cool weather, summer has arrived in Maine, and weather conditions are expected to turn very hot and humid this week. Forecasts suggest that the heat wave will begin on Tuesday, impacting much of the state, and could become record-breaking on Wednesday and Thursday before easing by the weekend. Overnight temperatures are expected to remain high, preventing people from getting relief and causing heat to build up in buildings without air conditioning.
Hot weather conditions like these can cause heat-related illnesses such as heat stroke, exacerbate chronic health conditions, and lead to severe complications and death. Extreme heat is infrequent in Maine, and high humidity levels make it feel even hotter by preventing the body from cooling itself efficiently through sweating. Residents and visitors may not be well-adapted to these conditions, and rates of home air conditioning, one of the best preventative factors for heat-related illness, are some of the lowest in the country. These factors put all Mainers at risk of heat-related illness. Many Mainers are more vulnerable to heat-related illness because of older age, chronic health conditions, or other factors.
Maine CDC encourages health care providers, caregivers, and public health professionals to recognize the threat that extreme heat poses to health, to become familiar with new U.S. CDC resources for clinicians, and to share relevant messages with those in their care.

| Maine CDC recently received notification of an infant with perinatally acquired HIV infection. The last infant in Maine with HIV infection attributed to perinatal transmission was born in 2019. Perinatal HIV infections are rare, with 21 cases of HIV attributed to perinatal transmission in the U.S. in 2021, the last year for which data are available. Perinatal HIV in the U.S. has fallen by more than 95% since the early 1990s. Perinatal HIV transmission occurs when HIV is passed from a pregnant person to their child during pregnancy, childbirth, or breastfeeding/chestfeeding. Having an undetectable viral load in pregnancy, and throughout the duration of breastfeeding/chestfeeding, lowers the risk of perinatal transmission of HIV to <1%. Most pregnant people living with HIV can have vaginal deliveries: for people with a high viral load (>1,000 copies/mL) near the time of delivery, a scheduled cesarean delivery can reduce the risk of perinatal HIV transmission. |

| Please take a moment to review this information on highly pathogenic avian influenza A(H5N1) in the U.S.
The Centers for Disease Control and Prevention (U.S. CDC) is issuing this Health Alert Network (HAN) Health Advisory to inform clinicians, state health departments, and the public of a recently confirmed human infection with highly pathogenic avian influenza (HPAI) A(H5N1) virus in the United States following exposure to presumably infected dairy cattle. The U.S. Department of Agriculture (USDA) recently reported detections of highly pathogenic avian influenza A(H5N1) virus in U.S. dairy cattle in multiple states. This Health Advisory also includes a summary of interim U.S. CDC recommendations for preventing, monitoring, and conducting public health investigations of potential human infections with HPAI A(H5N1) virus.
Highly pathogenic avian influenza (HPAI) A(H5N1) continues to circulate in Maine with recent detections in wild and domestic birds. HPAI A(H5N1) can infect humans and cause illness. The risk to the general public remains low. People who are directly exposed to HPAI A(H5N1) should monitor for symptoms and get tested if symptomatic.
Maine Health and Environmental Testing Laboratory (HETL) is the only laboratory in Maine capable of testing for HPAI A(H5N1). Respiratory specimens from symptomatic patients with recent contact to sick or dead birds or animals suspected of having HPAI A(H5N1) should be sent to HETL following the influenza laboratory submission information sheet (LSIS) found at https://www.maine.gov/dhhs/mecdc/public-health-systems/health-and-environmental-testing/micro/documents/Detection-of-Influenza-by-Real-Time-RT-PCR-LSIS.pdf All questions and concerns regarding human cases of HPAI A(H5N1) and human exposures to HPAI A(H5N1) should be directed to Maine CDC by calling the 24-hour disease reporting line at 800-821-5821.
Health care providers/facilities should have processes in place to identify and isolate persons with possible HPAI A(H5N1), inform infection control, and manage health care exposures.

| The Maine Center for Disease Control and Prevention (Maine CDC) has identified three additional new HIV diagnoses among people who inject drugs (PWID) in Penobscot County. There are now a total of six confirmed cases associated with this cluster; five of the newly diagnosed individuals were unhoused at the time of their diagnosis. Some of the individuals recently diagnosed with HIV had previous contact with the health care system, including missed opportunities for HIV testing.
Clinicians should increase vigilance for signs and symptoms of acute HIV and to increase testing for HIV and HCV. Patients may not disclose risk factors. U.S. Centers for Disease Control and Prevention (U.S. CDC) recommends HIV testing at least once for those 13 to 64, or more often for those with ongoing risk factors. HCV testing is recommended at least once for those 18 and older, utilizing an opt-out approach.
Following the recent detection of this cluster of HIV diagnoses, Maine CDC recommends testing people with ongoing risk factors, statewide, at least every three months.

| Please take a moment to review this information on measles circulation in the U.S. and globally and consider what you can do to prepare for the possibility of measles cases in Maine in the near future.
The Centers for Disease Control and Prevention (U.S. CDC) is issuing this Health Alert Network (HAN) Health Advisory to inform clinicians and public health officials of an increase in global and U.S. measles cases and to provide guidance on measles prevention for all international travelers aged 6 months and all children aged 12 months who do not plan to travel internationally. Measles (rubeola) is highly contagious; one person infected with measles can infect 9 out of 10 unvaccinated individuals with whom they come in close contact.
From January 1 to March 14, 2024, U.S. CDC has been notified of 58 confirmed U.S. cases of measles across 17 jurisdictions, including seven outbreaks in seven jurisdictions compared to 58 total cases and four outbreaks reported the entire year in 2023. Among the 58 cases reported in 2024, 54 (93%) were linked to international travel. Most cases reported in 2024 have been among children aged 12 months and older who had not received measles-mumps-rubella (MMR) vaccine. Many countries, including travel destinations such as Austria, the Philippines, Romania, and the United Kingdom, are experiencing measles outbreaks. To prevent measles infection and reduce the risk of community transmission from importation, all U.S. residents traveling internationally, regardless of destination, should be current on their MMR vaccinations. Healthcare providers should ensure children are current on routine immunizations, including MMR. Given currently high population immunity against measles in most U.S. communities, the risk of widescale spread is low. However, pockets of low coverage leave some communities at higher risk for outbreaks.
Maine has not seen any cases of measles since 2019. The U.S. CDC is reporting a sharp increase in measles cases this year, already exceeding the total for 2023. As of April 11, a total of 121 measles cases had been reported by 18 jurisdictions, including Arizona, California, Florida, Georgia, Illinois, Indiana, Louisiana, Maryland, Michigan, Minnesota, Missouri, New Jersey, New York City, New York State, Ohio, Pennsylvania, Virginia, and Washington. Additional updates are available at https://www.cdc.gov/measles/cases-outbreaks.html.
All suspected cases of measles should be reported to Maine CDC immediately by phone to 1-800-821-5821.
Maine CDC prefers measles specimen for PCR testing be submitted to the Maine Health and Environmental Testing Laboratory (HETL) so results can be better tracked, or they can be submitted to other laboratories.
Health care facilities should prepare for the possibility of patients with measles presenting to their facilities in the near future.

| U.S. CDC is reporting an increase in invasive meningococcal disease in the U.S. in 2024, mainly attributable to Neisseria meningitidis serogroup Y. Most cases involve a single sequence type, ST-1466. Most of the patients are between 30-60 years old, are Black or African American, or are living with HIV. In addition, most cases caused by this strain had a clinical presentation other than meningitis, such as bacteremia and septic arthritis. |

| Measles activity in the United States is now the highest it has been since 2019. Between January 1 and February 29, 2024, 16 U.S. jurisdictions reported a total of 41 cases. Most of these cases were among children and adolescents who had not received a measles-containing vaccine (measles-mumps-rubella [MMR] or measles-mumps-rubella-varicella [MMRV]), even if age-eligible. Health care facilities should have plans and processes in place to rapidly identify, isolate, and inform Maine CDC of any suspected measles cases. Health care providers should be on alert for patients who have febrile rash illness and symptoms consistent with measles (e.g., cough, coryza, or conjunctivitis) and have recently traveled, especially to states or countries with ongoing measles outbreaks. Infected people are contagious from four (4) days before the rash starts through four (4) days after the rash starts. |

| From October 2023 through February 23, 2024, Maine Center for Disease Control and Prevention (Maine CDC) has identified three new HIV diagnoses among people who inject drugs (PWID) in Penobscot County. Two of the individuals were unhoused and reported sharing or reusing injection drug equipment. All three individuals were coinfected with hepatitis C virus (HCV). Over the past five years, there have been an average of two new HIV diagnoses per year in Penobscot County residents and one new case per year among PWID in Penobscot County. In response to this increase in HIV diagnoses among PWID, Maine CDC is working with community partners to increase access to HIV and HCV testing among people at risk. |

|
| Respiratory virus transmission in the United States has increased in recent weeks and is expected to peak in coming weeks, leading to more infections, serious illness, hospitalizations, and deaths as well as more health care workers out of work due to illness. When there is higher respiratory virus transmission, health care facilities should implement policies requiring staff to wear appropriate masks or respirators for source control and infection control either during patient interactions or at all times inside facilities. Health care facilities should also consider requiring COVID-19 vaccine for patient-facing staff alongside the existing state requirements for influenza vaccine.
Comprehensive infection prevention and control policies, including masking and vaccination, protect staff, patients, residents, and visitors. Health care facilities should consider these demonstrated risk-reduction measures as they adapt to the shifting community situation. Masking protects the wearer and others around them against respiratory virus infections. Vaccines provide the best protection against severe illness. The Maine CDC remains dedicated to preventing severe disease and death from respiratory viral illnesses, particularly for populations at higher risk, and continues to work to reduce their impacts. |

| COVID-19 continues to circulate in our communities and continues to cause hospitalizations and deaths. Access to timely testing and outpatient treatment is crucial to reducing severe disease. Two oral antiviral drugs, Paxlovid and Lagevrio, previously freely available, are now commercially available. Most people will still be able to access treatment in a timely manner at pharmacies or health care facilities. Uninsured or underinsured people may face new barriers to treatment access, and new patient assistance programs are now available to support these populations. Providers should become familiar with these changes to COVID-19 antiviral access and insurance coverage to support their patients and help ensure timely care. Facilities offering COVID-19 antiviral drugs to their patients should order from commercial distributors now and should prepare to assist all patients with obtaining COVID-19 treatment via multiple pathways. |

|
| The Centers for Disease Control and Prevention (U.S. CDC) is issuing this Health Alert Network (HAN) Health
Advisory to alert healthcare providers to low vaccination rates against influenza, COVID-19, and RSV (respiratory syncytial virus). Low vaccination rates, coupled with ongoing increases in national and international respiratory disease activity caused by multiple pathogens, including influenza viruses, SARS-CoV-2 (the virus that causes COVID-19), and RSV, could lead to more severe disease and increased healthcare capacity strain in the coming weeks. In addition, a recent increase in cases of multisystem inflammatory syndrome in children (MIS-C) following SARS-CoV-2 infection in the United States has been reported. Healthcare providers should administer influenza, COVID-19, and RSV immunizations now to patients, if recommended. Healthcare providers should recommend antiviral medications for influenza and COVID-19 for all eligible patients, especially patients at high-risk of progression to severe disease such as older adults and people with certain underlying medical conditions. Healthcare providers should also counsel patients about testing and other preventive measures, including covering coughs/sneezes, staying at home when sick, improving ventilation at home or work, and washing hands to protect themselves and others against respiratory diseases.

| Hospital emergency departments, emergency medical services, and outpatient providers should be on alert for carbon monoxide (CO) poisonings. The Maine Center for Disease Control and Prevention (Maine CDC) is investigating 18 reports of CO poisoning from eight separate incidents linked to improper generator use after the recent storm. CO poisoning is a reportable condition in Maine and these events have been reported to the Maine CDC. The Maine CDC investigates cases of suspected CO poisoning to identify exposure risk factors and improve outreach efforts to prevent further poisonings.
All of these CO poisonings are due to improper operation of gasoline-powered generators such as operation in enclosed spaces like garages or basements. As single portable gas-powered generator can produce as much deadly CO gas as 100 idling cars. Improper use of portable gas-powered generators in enclosed or partially enclosed spaces can quickly cause CO poisoning, which can be fatal.

| The Centers for Disease Control and Prevention (U.S. CDC) is issuing this Health Alert Network (HAN) Health Advisory to notify healthcare providers and the public about an outbreak of Rocky Mountain spotted fever
(RMSF) among people in the United States with recent travel to or residence in the city of Tecate, state of Baja California, Mexico. RMSF is a severe, rapidly progressive, and often deadly disease transmitted by the bite of infected ticks, although many patients do not recall being bitten by a tick. Doxycycline is the treatment of choice for patients of all ages. As of December 8, 2023, five patients have been diagnosed with confirmed RMSF since late July 2023; all had travel to or residence in Tecate within 2 weeks of illness onset. RMSF is endemic in multiple border states in northern Mexico, including but not exclusive to Baja California, Sonora, Chihuahua, Coahuila, and Nuevo Len. Healthcare providers should consider RMSF in their differential diagnosis of patients who have reported recent travel to Tecate, Mexico, or other areas of northern Mexico and subsequently develop signs or symptoms of an unexplained severe febrile illness. Consider initiating doxycycline based on presumptive clinical and epidemiologic findings, and do not delay treatment pending the result of a confirmatory laboratory test. Early treatment with doxycycline saves lives.

| The Centers for Disease Control and Prevention (U.S. CDC) is issuing this Health Alert Network (HAN) Health Advisory to notify clinicians and health departments about the occurrence, geographic spread, and sexually associated human-to-human transmission of Clade I Monkeypox virus (MPXV) in the Democratic Republic of the Congo (DRC). MPXV has two distinct genetic clades (subtypes), and cases of Clade I MPXV have not been reported in the United States at this time (a clade is a broad grouping of viruses that has evolved over decades and is a genetic and clinically distinct group). However, clinicians should be aware of the possibility of Clade I MPXV in travelers who have been in DRC. Clinicians should notify the Maine CDC if they have a patient with mpox-like symptoms, which may include a diffuse rash and lymphadenopathy, and recent travel to DRC. Clinicians should also submit lesion specimens for clade-specific testing for these patients. |

| Maine continues to see a record-breaking burden of human tickborne disease. As of December 7, 2023, Maine reported 2,706 cases of Lyme disease, 738 cases of anaplasmosis, 173 cases of babesiosis, 12 cases of hard tick relapsing fever, and five cases of Powassan. The Maine Center for Disease Control and Prevention (Maine CDC) reported record numbers of Lyme disease and Powassan surpassing the 2,652 Lyme disease cases and four Powassan cases reported in 2022. Maine also reported five cases of alpha-gal syndrome (not a reportable illness) and two cases of ehrlichiosis, which are both considered travel-related conditions in Maine. While cooler temperatures mean less tick activity, ticks may still seek human hosts whenever temperatures are above freezing. Mainers and visitors who spend time outdoors, particularly on warmer winter days, are at risk of exposure to tick bites and subsequent tickborne illness. Clinicians should consider testing for tickborne diseases in patients presenting with febrile illnesses (100.4F or 38C) year-round. |

| Influenza, COVID-19, and respiratory syncytial virus (RSV) are three viral respiratory infections that cause the majority of respiratory-related hospitalizations and deaths in our communities. Influenza and RSV cause seasonal epidemics with timing that varies year to year; COVID-19 burden continues to rise and fall with no seasonality. U.S. CDC's initial respiratory season outlook indicated that, with COVID-19, seasonal influenza, and RSV, even an average respiratory season can place substantial strain on the health care system; U.S. CDC continues to anticipate that the upcoming fall/winter respiratory disease season will likely result in a similar number of hospitalizations as last years respiratory virus season. It is crucial for Maine clinicians to stay up to date with the latest information about prevention, testing, and treatment for these three respiratory infections to reduce the burden of severe disease on our population. |

| The National Weather Service, in coordination with the National Hurricane Center, is reporting that Maine will experience impacts from Hurricane Lee beginning Friday night into Saturday morning due to a westward shift in the storm track and widening storm radius. The storm is predicted to slowly weaken to a Category 1 storm and eventually downgrade to a tropical storm as it makes landfall. Tropical storm force winds, coastal flooding and high surf, and riverine flooding are all possible impacts from the storm. Central Maine Power has said that Maine could see impacts to the power grid which could be worsened due to the heavy rainfall received this summer and the risk of fallen trees or branches. Health care providers can help Mainers prepare for and respond to the hurricane. |

| Vibriosis is caused by Vibrio bacteria that naturally live in certain coastal waters. Most infections occur after eating raw or undercooked shellfish. Some types of Vibrio cause skin infections when an open wound is exposed to salt water or brackish water. Individuals with immunocompromising conditions or chronic liver disease are most likely to be infected with Vibrio. Eating raw seafood and coming into contact with salt water or brackish water can increase the likelihood of acquiring the disease.
Symptoms of vibriosis acquired through ingestion may include abdominal pain, nausea, vomiting, diarrhea, and fever. Symptoms typically begin within 24 hours of ingestion. Most mild cases recover within three days. However, severe cases may require hospitalization. Symptoms of vibriosis acquired through wounds may include fever, redness, pain, swelling, warmth, discoloration, and discharge.
As of September 5, 2023, there have been 12 reported probable and confirmed cases of vibriosis in Maine residents this year. The majority of vibriosis cases are reported in the summer and fall months when the coastal waters are warmer.

| Particle pollution concentrations are expected to reach "Unhealthy for Sensitive Groups" (USG) level Wednesday September 6th, according to the Maine Department of Environmental Protection (DEP). A dense ground-level plume of smoke from fires in Canada moved into Maine last night. For today, the 24-hour average is expected to be in the USG range for the northern region. For the remainder of the state, the 24-hour average is expected to be Moderate with only a few hours above Moderate. In addition, temperatures across the state are unseasonably warm, which could present additional risk to those spending time outdoors. At elevated particle pollution levels, children, healthy adults who exert themselves, and individuals suffering from a respiratory disease such as asthma, bronchitis or COPD can experience reduced lung function and irritation. When this happens, individuals may notice a shortness of breath, coughing, throat irritation, and/or experience an uncomfortable sensation in their chest. Additionally, those with a heart disease should also follow these recommendations. |

In addition to the clinical resources available here, you can also learn more about the clinical management of malaria from the recent U.S. CDC Clinician Outreach and Communication Activity (COCA) call held on July 20, 2023. A recording of that webinar is available at https://emergency.cdc.gov/coca/calls/2023/callinfo_072023.asp.
In Maine, Anopheles mosquito vectors are present. While the risk in Maine remains low, it is possible for local mosquitoes to acquire Plasmodium spp. parasites from an infected person and transmit the parasites to a susceptible, non-infected person.
Providers should consider a malaria diagnosis in patients with unexplained febrile illnesses, particularly patients returning from areas with local malaria transmission. Confirmed and suspected patients with malaria should be reported to Maine CDC. Providers with questions about malaria diagnosis and treatment can call the U.S. CDC Malaria Hotline at 770-488-7788.

| Please review this helpful information about domestic acquisition of malaria in the U.S. in recent months, risks of acquisition of malaria in the U.S. with increased international travel, and the need to plan for testing and treatment of patients with malaria.
In Maine, Anopheles mosquito vectors are present. While the risk in Maine remains low, it is possible for local mosquitoes to acquire Plasmodium spp. parasites from an infected person and transmit the parasite to a susceptible, non-infected person. Providers should encourage confirmed and suspected patients with malaria to avoid activities that would put them in contact with local mosquitoes.
The above average rainfall in the previous weeks increases the chance of a potentially more robust mosquito season. Providers should remain vigilant throughout the year for potential cases. All confirmed and suspected patients with malaria must be reported to Maine CDC by electronic laboratory reporting, fax at 800-293-7534, or by phone at 800-821-5821.

| March 24 is World TB Day. World TB Day is a time to recognize achievements and to renew our commitment to ending tuberculosis (TB) in the United States.
Recognize the signs and symptoms of TB disease, test for TB infection, and treat latent TB infection (LTBI) and TB disease.
Consider TB disease in patients with symptoms such as hemoptysis, fatigue, loss of appetite, weight loss, night sweats, fever, and cough for more than 3 weeks, regardless of presence/absence of risk factors for TB disease.
TB testing is recommended for patients with risk factors for becoming infected with TB such as foreign-born persons from countries with elevated rates of TB and history of working or living in a congregate setting (i.e., homeless shelters, correctional facilities, detention centers, and long-term care facilities).
Timely completion of TB treatment is critical. Treatment for both LTBI and TB disease should be initiated early to avoid disease progression and further spread of TB. Make sure patients take all doses as prescribed to prevent severe disease and death, decrease risk of developing multi-drug resistance, and mitigate spread of TB to others.

| Please review this advisory on the potential for chikungunya infection after travel to Paraguay. Consider testing for chikungunya in patients with unexplained encephalitis, meningitis, fever, or polyarthralgia. Chikungunya is a serious arboviral infection transmitted from the bite of an infected mosquito. Maine does not have mosquitoes that transmit this virus and there is no risk of local transmission. Most people are infected while travelling abroad to an area with known chikungunya activity. This disease has potentially severe and even fatal consequences for those who contract it. Maine's Health and Environmental Testing Laboratory (HETL) can test for chikungunya.
If you suspect chikungunya infection, you may submit serum and CSF samples to HETL for arboviral testing. Chikungunya is a reportable disease. All suspect cases and positive lab reports should be reported to Maine CDC by phone to the 24/7 disease reporting and consultation line at 1-800-821-5821 or by fax to 1-800-293-7534. |

Measles is a reportable condition: cases should be reported immediately to Maine CDC at 800-821-5821 on recognition or strong suspicion of disease. Labs should submit isolates and clinical specimens to Maine CDC for confirmation. Antibody and PCR testing can be performed at some commercial laboratories.
PCR testing can be performed at Maine's Health and Environmental Testing Laboratory (HETL). If a commercial laboratory is used, Maine CDC may request that clinical specimens be sent to HETL for confirmational testing.
Maines MMR vaccination coverage is higher than the national average (96.7% of kindergarteners have 2+ doses compared to 93.6% nationally). Unvaccinated individuals, especially children under 5 years old, pregnant people, and individuals with compromised immune systems are more likely to suffer from measles complications. |

| As of February 15, 2023, a total of 30,193 cases of mpox and 32 deaths have been reported nationwide as part of the 2022 mpox outbreak. Mpox case counts have fallen in recent months, from an average of over 400 cases a day in August 2022 to less than five per day in February 2023. Thirteen mpox cases were reported in Maine residents in 2022 (preliminary data as of February 28, 2023) and no cases have been reported so far in 2023.
In the current outbreak, most people have been infected during sexual activity from contact with mpox lesions on the skin or mucosal surfaces, such as the throat, anus, or rectum, of a person with mpox. Gay, bisexual, and other men who have sex with men make up the majority of cases. Anyone, regardless of sexual orientation or gender identity, can become infected with mpox if they have close or intimate contact with someone who is pre-symptomatic for or has symptoms of mpox.

| Massachusetts recently identified a novel strain of multidrug-non-susceptible Neisseria gonorrhoeae (N. gonorrhoeae) with resistance or reduced susceptibility to all drugs that are recommended for treatment in the U.S. The novel strain, identified in Massachusetts, showed reduced susceptibility to ceftriaxone, cefixime, and azithromycin and showed resistance to ciprofloxacin, penicillin, and tetracycline. This is the first isolate identified in the U.S. showing resistance or reduced susceptibility to all drugs that are recommended for treatment. This strain has the same sequence type recently identified in the United Kingdom and previously reported as circulating in Asia-Pacific countries. Identification of this novel strain is a reminder that N. gonorrhoeae is becoming less responsive to a limited arsenal of antibiotics.
While no cases of this novel strain have been reported in Maine as of today's date, gonorrhea continues to be a concern, with cases rising nationally and in Maine. Cases of gonorrhea in Maine increased 34% between 2021 (n=462) and 2022 (n=620). In 2022, rates of gonorrhea were highest for Black and African Americans, males, and persons aged 15-34 years; one-third of cases reported male-to-male sexual contact (2022 data as of February 2, 2023). The highest rate of gonorrhea in Maine was in Androscoggin County (122.5 cases per 100,000 population). |

| The U.S. Food and Drug Administration (FDA) announced on January 26, 2023, that the Emergency Use Authorization (EUA) for Evusheld (tixagevimab co-packaged with cilgavimab) has been revised and based on this revision, Evusheld is not currently authorized for use in the U.S. This is because it is unlikely to be active against more than 90% of the SARS-CoV-2 variants currently circulating in the U.S. based on the latest CDC data. However, people who have used Evusheld still have options to increase their protection against the most serious consequences of COVID-19, including hospitalization and death. |

| Syphilis rates in the United States (U.S.) have been increasing since 2012. From 2012 through 2021, the rate of syphilis cases increased by 224% in the U.S. and by 405% in Maine. In 2022, 112 cases of syphilis were reported in Maine, 20.5% of whom were women between the ages of 15 and 44 years (preliminary data).
Maine CDC recently received notification of a case of probable congenital syphilis (CS). This is the first case of CS reported in a Maine resident in nearly 30 years. In 2021, there were 2,677 cases of CS reported in the U.S., an increase of 702% from 2012. In 2021, the highest rates of CS were among birthing persons who were non-Hispanic American Indian or Alaska Native (364 cases per 100,000 live births), non-Hispanic Native Hawaiian or other Pacific Islander (221 cases per 100,000 live births), and non-Hispanic Black or African American (153 cases per 100,000 live births).
CS occurs when a pregnant person with syphilis passes the infection to the fetus during pregnancy. This can happen during any stage of syphilis and any trimester of pregnancy; the risk of transmission is highest if the pregnant person has been infected recently. Approximately 40% of babies born to persons with untreated syphilis can be stillborn or die from the infection as a newborn. CS can lead to preterm labor and newborn/childhood illness including hydrops fetalis; hepatosplenomegaly; rashes; fevers; failure to thrive; deformity of the face, teeth, and bones; blindness; and deafness. Adequate and timely treatment of syphilis in pregnant persons is 98% effective in preventing CS. During 2017 through 2021, the majority of missed prevention opportunities among persons delivering babies with CS in the U.S. were those with no timely prenatal care or syphilis testing (38% of cases) and those with timely syphilis testing but no adequate treatment of the pregnant person (34% of cases).

| Syphilis cases have been increasing in Maine over the past several years, particularly among women.
The increase in syphilis cases among women of reproductive age is concerning because of the potential risk of congenital syphilis if she is pregnant.
All pregnant persons at the first prenatal visit, and retest at 28 weeks gestation and at delivery if at high risk
Maine CDC recommends testing for syphilis in all patients who are obtaining any sexually transmitted infection (STI) testing.
Providers should presumptively treat if a patient is symptomatic, is a contact to a syphilis case, belongs to a high-risk group, or if follow-up is uncertain.

| FDA today revoked the emergency use authorization for bebtelovimab, a monoclonal antibody therapy. Accordingly, bebtelovimab may no longer be used for COVID-19 treatment in the U.S. With the continued appearance of new variants, COVID-19 infection is now likely to be due to variants resistant to all monoclonal antibody therapies. Healthcare facilities offering COVID-19 monoclonal antibody treatment should explore offering Veklury to patients who cannot receive Paxlovid and should retain outpatient infusion capacity for COVID-19 monoclonal antibody therapies that could be authorized later. |

1) Severe manifestations of monkeypox have been observed in the United States in the current outbreak.
2) People who are immunocompromised due to HIV or other conditions are at higher risk for severe manifestations of monkeypox than people who are immunocompetent.
3) Because people with HIV-associated immunocompromise are at risk for severe manifestations of monkeypox, the HIV status of all sexually active adults and adolescents with suspected or confirmed monkeypox should be determined.
4) There are diagnostic and clinical management strategies that may help address severe manifestations of monkeypox.

|
| Healthcare providers and hospitals in several regions of the United States notified the Centers for Disease Control and Prevention (U.S. CDC) during August 2022 about increases in pediatric hospitalizations in patients with severe respiratory illness who also tested positive for rhinovirus (RV) and/or enterovirus (EV). RVs and EVs can have clinically similar presentations and are indistinguishable from one another on multiplex assays often used in clinical settings. Upon further typing, some specimens have been positive for enterovirus D68 (EV-D68). Concurrently, pediatric acute respiratory illness sentinel surveillance sites are reporting a higher proportion of EV-D68 positivity in children who are RV/EV positive compared to previous years. Although it primarily causes acute respiratory illness, EV-D68 has been associated with acute flaccid myelitis (AFM), a rare but serious neurologic complication involving limb weakness.
The purpose of this Health Alert Network (HAN) Health Advisory is to
1. Notify healthcare providers, laboratories, infection control specialists, and public health departments about recent increases in severe respiratory illness requiring hospitalization in children,
2. Urge healthcare providers to consider EV-D68 as a possible cause of acute, severe respiratory illness (with or without fever) in children,
3. Advise of the potential for an increase in AFM cases in the upcoming weeks, and
4. Provide U.S. CDC and Maine CDC recommendations to healthcare providers, laboratories, infection preventionists, and the public.

| The Maine Center for Disease Control and Prevention (Maine CDC) has received several reports of positive influenza laboratory results during recent weeks. Maine CDC is requesting that laboratories send respiratory specimens from influenza confirmed or suspect patients to Maine's Health and Environmental Testing Laboratory (HETL) for subtyping, especially in the beginning of influenza season. Subtyping allows Maine CDC to determine which influenza viruses are circulating this season and detect novel influenza virus infections.
Novel influenza A viruses cause human infection but are different from current seasonal human influenza A viruses that circulate among people. In August 2022, U.S. CDC reported 5 cases of human variant virus infection, or viruses that typically circulate in swine, and avian influenza H5N1 continues to circulate in wild and domestic birds. Though the risk to humans remains low, healthcare providers should be aware and test symptomatic patients with risk factors such as swine, agriculture, and avian exposures for influenza. HETL is the only laboratory in Maine that can identify novel influenza, therefore, all influenza A positive specimens from people with these exposures should be sent to HETL for further evaluation.

| In 2021, providers reported 63 cases of varicella in Maine residents to Maine CDC, compared to just 33 cases reported in 2020. The decrease in widespread COVID-19 social distancing practices likely played a role in the increase in varicella cases. Varicella is a notifiable condition in Maine, and all confirmed or suspected cases should be reported to Maine CDC by telephone, fax, or electronic lab report within 48 hours of recognition or strong suspicion of disease. |

| In 2014, national surveillance began for Acute Flaccid Myelitis (AFM). Peaks of cases were observed across the United States in 2014, 2016, and 2018. Given the observed biennial pattern, it was anticipated that there would be an increase in AFM cases in 2020; however, cases plateaued from 2019 through 2021. It is likely that methods of prevention for COVID-19 contributed to the deviation from the previously observed biennial pattern. AFM is still observed across the country; it is unknown if the biennial pattern will resume.
The U.S. Centers for Disease Control and Prevention (U.S. CDC) reported eight confirmed cases of AFM from January 2022 through June 2022. Enteroviruses, particularly EV-D68, are thought to be a likely cause of the condition. AFM is rare in Maine, with four confirmed cases reported since 2014. Common symptoms include respiratory or gastrointestinal illness, rapid onset of limb weakness in one or more limbs (more proximal), loss of muscle tone and reflexes in the affected limb or limbs, facial or eyelid droop and difficulty swallowing or speaking. In severe cases, AFM can lead to respiratory failure or neurologic life-threatening complications. The condition progresses rapidly and can lead to respiratory failure, so early detection and hospitalization are critical.

| The purpose of this health advisory is to alert clinicians to the potential for human arboviral disease activity in Maine and to consider testing for mosquito-borne arboviruses in patients presenting with unexplained encephalitis, meningitis, or high fever (≤100.4°F or 38°C) during the summer and fall. Consider testing for Powassan virus year-round.
Eastern Equine Encephalitis virus (EEE), Jamestown Canyon virus (JCV), and West Nile virus (WNV) are serious arboviral infections that are transmitted by the bite of an infected mosquito. Maine reported one human case of JCV in 2021. Additionally, Powassan virus (POW) is an arboviral disease transmitted by the bite of an infected tick. Maine identified three cases of POW in 2021 and four more cases to date in 2022. Two of the POW cases in 2022 died. Although rare, these diseases have potentially severe and even fatal consequences for those who contract them.

|
| COVID-19 remains a major health concern in Maine and across the United States. COVID-19 was the third leading cause of death in the U.S. in 2020 and 2021. New variants continue to emerge, some with higher transmissibility and an ability to cause breakthrough infections in those who have been vaccinated and in those with prior COVID-19 infection. Vaccination remains the best protection against infection, hospitalization, and death. Vaccines are available for people 6 months and older and boosters are available for people 5 years and older; additional doses and other pre-exposure prophylaxis for people with moderate/severe immunocompromise. People should keep up to date on COVID-19 vaccination. Getting vaccine doses now will not preclude receiving additional vaccine doses in the fall or beyond.
Maine continues to see COVID-19 hospitalizations and deaths, largely among younger, unvaccinated adults and older, vaccinated adults. In people with mild or moderate COVID-19 illness who are at high risk for severe disease, treatment can sharply reduce the risk of progressing to hospitalization or death. Outpatient treatment of COVID-19 is the standard of care for eligible patients. Health care providers, particularly those in primary care specialties, should become familiar with these therapeutics and how to prescribe them for appropriate patients. |

| Ground-level ozone concentrations will be climbing in Maine late Saturday evening, dropping off overnight then building up again on Sunday along the coast of Maine from Kittery through Acadia NP and are expected to reach unhealthy levels on Sunday according to the Maine Department of Environmental Protection (DEP). Ozone levels have been at or near unhealthy levels in southern New England for days. Winds Saturday evening will turn toward Maine in the Gulf of Maine continuing into Sunday. This will allow transport of ozone and its precursors from upwind sources such as southern New England and beyond to Maine. Meanwhile, particle pollution levels will likely be in the moderate range in southern portions of Maine. |

| The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Advisory to inform clinicians and public health departments that parechovirus (PeV) is currently circulating in the United States. Since May 2022, CDC has received reports from healthcare providers in multiple states of PeV infections in neonates and young infants. Parechoviruses are a group of viruses known to cause a spectrum of disease in humans. Clinicians are encouraged to include PeV in the differential diagnoses of infants presenting with fever, sepsis-like syndrome, or neurologic illness (seizures, meningitis) without another known cause and to test for PeV in children with signs and symptoms compatible with PeV infection (see below). Commercial laboratory assays, multiplex platforms for meningitis and encephalitis, and testing through state public health laboratories (SPHLs) are available to test cerebrospinal fluid (CSF) for PeV to confirm a diagnosis. CDC laboratory support is also available for testing and typing patient specimens. |

| The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Advisory to update healthcare providers, public health departments, and the public on the potential for recurrence of COVID-19 or "COVID-19 rebound." Paxlovid continues to be recommended for early- stage treatment of mild to moderate COVID-19 among persons at high risk for progression to severe disease. Paxlovid treatment helps prevent hospitalization and death due to COVID-19. COVID-19 rebound has been reported to occur between 2 and 8 days after initial recovery and is characterized by a recurrence of COVID-19 symptoms or a new positive viral test after having tested negative. A brief return of symptoms may be part of the natural history of SARS-CoV-2 (the virus that causes COVID-19) infection in some persons, independent of treatment with Paxlovid and regardless of vaccination status. Limited information currently available from case reports suggests that persons treated with Paxlovid who experience COVID-19 rebound have had mild illness; there are no reports of severe disease. There is currently no evidence that additional treatment is needed with Paxlovid or other anti-SARS-CoV-2 therapies in cases where COVID-19 rebound is suspected. |

| The U.S. Centers for Disease Control and Prevention (U.S. CDC) issued a Health Advisory to notify clinicians and public health authorities of a cluster of children identified with hepatitis and adenovirus infection. In November 2021, clinicians at a large children's hospital in Alabama notified U.S. CDC of five pediatric patients with significant liver injury, including three with acute liver failure, who also tested positive for adenovirus. All children were previously healthy. None had COVID-19.
Case-finding efforts at this hospital identified four additional pediatric patients with hepatitis and adenovirus infection for a total of nine patients admitted from October 2021 through February 2022; all five that were sequenced had adenovirus type 41 infection identified. In two patients, plasma samples were negative for adenovirus by quantitative polymerase chain reaction (qPCR), but both patients were positive when retested using whole blood. Two patients required liver transplant; no patients died. A possible association between pediatric hepatitis and adenovirus infection is currently under investigation. Cases of pediatric hepatitis in children who tested negative for hepatitis viruses A, B, C, D, and E were reported earlier this month in the United Kingdom, including some with adenovirus infection.
This Health Advisory serves to notify clinicians who may encounter pediatric patients with hepatitis of unknown etiology to consider adenovirus testing and to elicit reporting of such cases to state public health authorities and to U.S. CDC. Nucleic acid amplification testing (NAAT, e.g., PCR) is preferred for adenovirus detection and may be performed on respiratory specimens, stool or rectal swabs, or blood.

| Human Immunodeficiency Virus (HIV) cases in Kennebec County, Maine, have increased from 1 case in 2020 to 5 cases in 2021 (see Figure 1). Of the 5 cases diagnosed in 2021, 4 were diagnosed when severely ill and hospitalized; 3 were diagnosed with AIDS (Acquired Immune Deficiency Syndrome) at the same time as their HIV diagnosis. The Maine CDC has not identified an epidemiological link among these cases at this time. Individuals who are diagnosed later in their HIV infection course are more likely to transmit HIV to others, and also have a poorer prognosis than those diagnosed earlier. |

| COVID-19 transmission continues to occur in Maine. In recent weeks, new cases have dropped under 1,000 cases/day and, in recent days, under 500 cases/day. This is a sharp drop from the recent surge of Omicron-variant infections in Maine in January and February, yet it does not mean we are in the clear. Over 30 COVID-19 deaths were reported to Maine CDC in the first half of March. The daily census of hospitalized COVID-19 patients, over 400 through much of January, just recently dipped below 100. Recent reports from European countries and elsewhere suggest the BA.2 subvariant is likely to cause a resurgence in cases, hospitalizations, and deaths in coming weeks. Many hospitalizations and deaths could be averted through early access to COVID-19 testing and COVID-19 outpatient treatment. |

| Maine Center for Disease Control and Prevention is investigating an increase in cases of Legionnaires' disease, a potentially fatal pneumonia, in persons who live in, work in, or visit York County. Providers should consider the possibility of Legionnaires disease in patients presenting with respiratory illness, particularly if the patient reports spending time in York County in the 14 days prior to the onset of symptoms. Providers should perform testing using both urine antigen and sputum/respiratory culture and consider using empiric treatment with activity against Legionella. |

| The United States Department of Agriculture (USDA) has confirmed highly pathogenic avian influenza (HPAI) A(H5N1) in a backyard bird flock in Knox County. This is the first time Maine has detected HPAI in the State. Though HPAI can cause illness in humans, no human cases with this specific viral strain have been detected in the United States to date.
Healthcare providers evaluating patients with respiratory symptoms should ask about recent exposures to wild and domestic birds and should consider influenza infection, including HPAI infection, as a possibility. Respiratory specimens collected from individuals with symptoms of influenza-like illness and bird exposures should be sent directly to Maine's Health and Environmental Testing Laboratory (HETL) for influenza testing.

| This health alert provides important updates regarding COVID-19 therapeutics for non-hospitalized patients, including new information on which patients to prioritize for some or all of these medications. It also includes information on locations in the State where patients can get tested, evaluated, and treated with these medications. The approach outlined in this health advisory is subject to change.
Vaccination remains the best way to prevent COVID-19 infection, hospitalization, and death. However, infections, hospitalizations, and deaths continue to occur in unvaccinated individuals and, to a lesser extent, in vaccinated individuals. Several oral and intravenous medications are now available in Maine to prevent progression of COVID-19 infection to hospitalization and death. However, lack of knowledge among patients, supply shortages of several of these medications, and other considerations such as transportation and insurance remain substantial barriers.

| This health alert provides an update on patient eligibility for EVUSHELD, a long-acting monoclonal antibody that is available under U.S. Food and Drug Administration Emergency Use Authorization for pre-exposure prophylaxis to prevent COVID-19 infection in persons with moderate to severe immunocompromise.
Vaccination for COVID-19 remains the best protection against infection, hospitalization, and death. However, individuals with immunocompromising conditions, or taking certain immunocompromising medications, may be less likely to mount an appropriate immune response to COVID-19 vaccination, leaving them at elevated risk for COVID-19 infection, hospitalization, and death. Many such persons are already at elevated risk for severe disease from COVID-19 due to their existing health conditions. Pre-exposure prophylaxis is now available for certain individuals who have been vaccinated against COVID-19 but remain highly susceptible to this infection and subsequent severe disease. |

| The Maine Center for Disease Control and Prevention (Maine CDC) relies on health care providers and laboratorians to report the occurrence of notifiable diseases. Without such surveillance data, Maine cannot accurately monitor trends, detect and respond to unusual occurrences of diseases (such as outbreaks), and evaluate the effectiveness of control and prevention activities.
COVID-19 is a reportable disease in Maine as stated in Maine CDC's Notifiable Diseases and Conditions List and Rules. Reporting of notifiable diseases and conditions is required under 22 M.R.S., Chapter 250, 802 and 822. Health care providers and facilities, medical laboratories, childcare facilities, correctional facilities, educational institutions, administrators, and health officers are all required reporters.

|
| On January 21, 2022, the U.S. Food and Drug Administration (FDA) granted full approval to the antiviral drug remdesivir (Veklury) to treat non-hospitalized patients 12 years of age and older with mild-to-moderate COVID-19 disease who are at high risk of hospitalization. This expanded approval provides another treatment option to reduce the risk of hospitalization in high-risk patients. The use of remdesivir was previously limited to patients requiring hospitalization, and treatment outside the hospital was off-label. Remdesivir's manufacturer, Gilead Sciences, Inc., indicates that it has been able to meet demand for this drug. In vitro data suggest that remdesivir remains active against the Omicron variant of SARS-CoV-2.
The expanded indication allows remdesivir to be administered in qualified outpatient settings that can administer daily intravenous (IV) infusions over three consecutive days. The FDA also expanded remdesivirs pediatric Emergency Use Authorization (EUA) to include non-hospitalized pediatric patients younger than 12 years of age (over 3.5 kg) who are at high risk of disease progression. |

| As of January 2, 2022, the Maine Center for Disease Control and Prevention (Maine CDC) is using updated definitions for COVID-19 outbreaks and COVID-19-associated deaths.
COVID-19 outbreak criteria will now depend on facility type. In pre-K-12 schools, an outbreak of COVID-19 will now be defined as greater than or equal to 15% absenteeism among students or staff in a single day, where the majority of those absent are due to COVID-19 illness. For all other facility types, including but not limited to long-term care, hospital, outpatient healthcare, higher education, and businesses, an outbreak of COVID-19 is now defined as 5 or more people who have been in-person at a facility with confirmed or probable COVID-19 within a 14-day period. |

| Advisory (PDF) |
| This health alert provides updates on (1) the use of monoclonal antibody therapies and (2) the availability of oral antivirals and infusion therapies for outpatients with COVID-19. This alert also contains information on how healthcare providers and patients can access oral antivirals and infusion therapies, which must be started in the first few days after symptom onset. Finally, this alert provides information on a long-acting monoclonal antibody therapy for pre-exposure prophylaxis in immunocompromised patients.
In short, given the increasing prevalence of the SARS-CoV-2 Omicron variant in the State, Maine CDC recommends healthcare providers suspend use of two monoclonal antibody therapies, bamlanivimab/etesevimab ("bam-ete") and casirivimab/imdevimab (REGEN-COV). A third monoclonal antibody therapy, sotrovimab, remains effective against the Omicron variant and should continue to be offered to patients meeting criteria.
With respect to oral antiviral therapies, Paxlovid and molnupiravir, Maine CDC is working with two pharmacy chains, Walmart and Hannaford, to make these therapies available across the State. More information will follow soon describing how to determine which patients should receive these therapies in the setting of limited availabilities. |

| The SARS-CoV-2 Omicron variant has quickly become the dominant variant of concern in the United States and is present in all 50 states. The Centers for Disease Control and Prevention (CDC) recommends that eligible individuals receive all vaccines and booster shots as the best preventive measure available against severe disease, hospitalizations, and death due to COVID-19. Therapeutics are also available for preventing and treating COVID-19 in specific at-risk populations. These therapeutics differ in efficacy, route of administration, risk profile, and whether they are authorized by the U.S Food and Drug Administration (FDA) for adults only or adults and certain pediatric populations. Some therapeutics are in short supply, but availability is expected to increase in the coming months. This Health Alert Network (HAN) Health Advisory serves to familiarize healthcare providers with available therapeutics, understand how and when to prescribe and prioritize them, and recognize contraindications. |

| Common Respiratory Illnesses Chart |
| Childhood respiratory illnesses like pertussis, respiratory syncytial virus (RSV), and influenza are circulating in Maine and should be considered in addition to COVID-19.
Schools and childcare programs should be aware of exclusion recommendations specific to pertussis. The most effective approaches to preventing and reducing transmission of pertussis include ensuring children are up-to-date on recommended vaccines (and maintaining vaccination records) and ensuring symptomatic staff and children stay home if they are sick with pertussis-like symptoms. Healthcare providers should be aware of pertussis or other alternative diagnoses for patients presenting with respiratory symptoms and should test appropriately.

| Respiratory syncytial virus (RSV) is circulating in Maine at a higher rate than usual for this time of year. Health care providers should consider testing patients with acute respiratory illness for RSV. To prevent transmission of RSV and other respiratory viruses, people with respiratory symptoms should refrain from in-person work, school, or daycare while acutely ill. This recommendation applies even if they have tested negative for SARS-CoV-2, the virus that causes COVID-19. |

| Maine CDC is seeing a rise in the number of reported cases of varicella (chickenpox). Varicella is a notifiable condition in Maine, and all confirmed or suspect cases of varicella should be reported to Maine CDC.
The number of reported cases of varicella decreased in 2020, likely due to reduced person-to-person transmission because of COVID-19 restrictions. Since January 1, 2021, Maine has identified 46 cases of varicella from all 16 counties (data as of 07/29/2021), including two outbreaks in child care facilities. |

| On July 1, 2021, Maine CDC issued a revised Standing Order ("Order") that authorizes health care providers or other trained personnel at a health care facility or medically supervised COVID collection site (collection site) in the state to collect and submit specimens of SARS-CoV-2 for molecular or antigen-based testing.
The Order is a physician's order that authorizes lab testing for COVID-19 for any individual in Maine at least 12 months of age or older. The Order is not meant to replace existing patient-provider relationships or provider-laboratory relationships. It can assist people who believe that they have been exposed or have an elevated risk of exposure and who do not have a primary care provider, cannot discuss this exposure in a timely way with their health care provider, or are visiting Maine from another state, as examples.
The Order also authorizes the collection site that submitted the specimen for SARS-CoV-2 molecular or antigen testing under this Order to receive the results of the test directly from the testing laboratory. The Order further authorizes the laboratory that performed the test for SARS-CoV-2 to provide test results directly to the individual who was tested, with the individuals consent.

| The purpose of this health advisory is to alert clinicians to the potential for human arboviral disease activity in Maine and to consider testing for arboviruses in patients presenting with unexplained encephalitis, meningitis or high fever (100.4F or 38C) during the summer and fall.
Maine CDC identified a human case of Powassan encephalitis in a Maine resident who resides in midcoastal Maine. The individual was symptomatic in late June and hospitalized. CDC Fort Collins confirmed the Powassan result in this individual by neutralization testing.
This individual likely acquired this Powassan encephalitis infection in the state of Maine. There are two types of Powassan virus in the United States. The first type, often called lineage 1 Powassan virus is associated with Ixodes cookei or the woodchuck tick. Lineage 2 POW, sometimes called Deer tick virus, is associated with Ixodes scapularis or the deer tick. Both can cause human disease. Powassan encephalitis is a member of the flavivirus genus which includes arboviruses like Dengue virus, West Nile virus (WNV), Yellow Fever virus, and Zika virus.
Arboviral diseases, including Eastern equine encephalitis (EEE), Jamestown Canyon virus (JCV), and WNV, are serious infections that are transmitted by the bite of an infected mosquito. Maine reported one human case of WNV in 2020. Additionally, Powassan virus is an arboviral disease transmitted by the bite of an infected tick. Maine identified one case of Powassan virus disease in residents during 2020. Although rare, these diseases have potentially severe and even fatal consequences for those who contract them.

| On Monday, June 28, 2021, the hours of operation for the clinical microbiology section at the Maine CDC Health and Environmental Testing Laboratory (HETL) will shift to 7 a.m. to 5 p.m., Monday through Friday. As a result, HETL will not conduct COVID-19 PCR testing on Saturday or Sunday.
Submitters should be aware that samples are only viable for testing within 72 hours after collection. Samples beyond that 72-hour window cannot be tested. Before 5 p.m. on Friday, HETL staff will freeze any sample that would expire because it is more than 72 hours post collection. HETL staff will then test that sample during the next business period. If HETL is not able to verify that an unfrozen sample was collected within 72 hours, the sample will not be tested.
Facilities should plan to deliver COVID-19 samples before 5 p.m. on Friday. Samples delivered after 5 p.m. on Friday may exceed the 72-hour period of viability prior to Monday. Samples received on Saturday or Sunday will be processed during the next business period, provided that the sample has not exceeded the 72-hour period of viability. |

Ground-level ozone concentrations will be climbing in Maine on Monday June 7th and are expected to reach unhealthy levels according to the Maine Department of Environmental Protection (DEP). Ozone levels have been high upwind since June 2nd. High levels began around Lake Michigan and have been slowly migrating eastward. By Saturday June 5th southern New England had very high levels of ozone even reaching into the Unhealthy (red) category. Transport winds are expected to direct the higher values to Maine on Monday. The unhealthy levels of ozone are possible along the entire coastline and the Eastern Interior. Meanwhile Particle Pollution levels are expected to be in the Moderate range.
At elevated ozone levels, children, healthy adults who exert themselves, and individuals suffering from a respiratory disease such as asthma, bronchitis or COPD can experience reduced lung function and irritation. When this happens, individuals may notice a shortness of breath, coughing, throat irritation, and/or experience an uncomfortable sensation in their chest.

| The Maine Center for Disease Control and Prevention (Maine CDC) has identified a case of acute hepatitis A virus infection in an Eastport, Maine, food service worker. The individual handled food in the deli at the R&M IGA at 88 Washington Street in Eastport, Maine, while infectious on the following dates in 2021: May 3-6, May 8, May 10-13, May 15, and May 18-20. Deli food items purchased on May 3-22 should be discarded or cooked thoroughly.
Epidemiological assessment of the employee's illness determined that patrons of the establishment may be at risk for hepatitis A infection. Maine CDC recommends that anyone who ate food prepared in the R&M IGA deli from May 13-22, 2021, receive hepatitis A vaccine within 14 days of their potential exposure. There is a 14-day window during which prophylaxis is effective after exposure.
Anyone who ate food prepared at or who worked at this establishment from May 3-12, 2021, is outside the window for which prophylaxis is recommended. Those individuals are advised to watch for symptoms and seek medical attention should they develop symptoms (see below). Health care providers are encouraged to remain vigilant for hepatitis A infection in persons with consistent symptoms and should ask individuals with such symptoms about consumption of prepared food from this establishment or who worked at this establishment during this period.

| The U.S. Centers for Disease Control and Prevention is aware of reports of myocarditis and pericarditis after receipt of a COVID-19 vaccine. The reports appear to be rare, given the number of vaccine doses administered to date. U.S. CDC is investigating whether there is any causal association or an increase of such events relative to the background rates.
Myocarditis is an inflammation of the heart muscle and pericarditis is the inflammation of the lining outside the heart. In both cases, the body's immune system causes an inflammation in response to an infection or some other trigger. While myocarditis can be serious, it is frequently mild and self-limited. Symptoms can include abnormal heart rhythms, shortness of breath, or chest pain. Myocarditis is often caused by a viral infection, but it can result from a reaction to a drug or as part of a more general inflammatory condition. Myocarditis itself not a notifiable condition in Maine.
Maine CDC has received reports of cases of myocarditis occurring in Maine residents after receipt of an mRNA COVID-19 vaccine. Since there is usually an increase in myocarditis at this time of year, it is not known if these cases are associated with receipt of the vaccine. Vaccination for COVID-19 remains strongly recommended. U.S. CDC will continue to evaluate reports of myocarditis/pericarditis occurring after COVID-19 vaccination and will share more information as it becomes available. |

| Maine CDC is forwarding this HAN message from US CDC to ensure widest visibility.
Maine CDC is not aware of any reports of these cases in Maine residents. The State of Maine is advising that providers pause administration of the Johnson & Johnson vaccine until the US CDC's scientific advisory committee has further reviewed the safety data. Maine CDC is working with administration partners to provide an alternative supply of the mRNA vaccines to clinics already scheduled so they can continue operations.
As of April 12, 2021, approximately 6.85 million doses of the Johnson & Johnson (J&J) COVID-19 vaccine (Janssen) have been administered in the United States. The Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) are reviewing data involving six U.S. cases of a rare type of blood clot in individuals after receiving the J&J COVID-19 vaccine that were reported to the Vaccine Adverse Events Reporting System (VAERS). In these cases, a type of blood clot called cerebral venous sinus thrombosis (CVST) was seen in combination with low levels of blood platelets (thrombocytopenia). All six cases occurred among women aged 18-48 years. The interval from vaccine receipt to symptom onset ranged from 613 days. One patient died. Providers should maintain a high index of suspension for symptoms that might represent serious thrombotic events or thrombocytopenia in patients who have recently received the J&J COVID-19 vaccine. When these specific type of blood clots are observed following J&J COVID-19 vaccination, treatment is different from the treatment that might typically be administered for blood clots. Based on studies conducted among the patients diagnosed with immune thrombotic thrombocytopenia after the AstraZeneca COVID-19 vaccine in Europe, the pathogenesis of these rare and unusual adverse events after vaccination may be associated with platelet-activating antibodies against platelet factor-4 (PF4), a type of protein. Usually, the anticoagulant drug called heparin is used to treat blood clots. In this setting, the use of heparin may be harmful, and alternative treatments need to be given.
CDC will convene an emergency meeting of the Advisory Committee on Immunization Practices (ACIP) on Wednesday, April 14, 2021, to further review these cases and assess potential implications on vaccine policy. FDA will review that analysis as it also investigates these cases. Until that process is complete, CDC and FDA are recommending a pause in the use of the J&J COVID-19 vaccine out of an abundance of caution. The purpose of this Health Alert is, in part, to ensure that the healthcare provider community is aware of the potential for these adverse events and can provide proper management due to the unique treatment required with this type of blood clot.

| The New Hampshire Department of Health and Human Services (DHHS) has notified the Maine Center for Disease Control and Prevention (Maine CDC) of multiple individuals with gastrointestinal illness associated with recent purchases of unpasteurized/raw milk from Brandmoore Farms in Rollinsford, NH. In subsequent investigations, Maine and New Hampshire public health officials have identified multiple cases of campylobacteriosis in residents of both states. Maine has identified at least 30 cases of campylobacteriosis among Maine residents associated with this outbreak. At least two Maine residents have been hospitalized.
Maine CDC and New Hampshire DHHS are warning consumers that they should not consume Brandmoore Farm retail raw milk with best-by dates through February 5, 2021. Anyone who consumed this raw milk has an elevated risk of enteric diseases, including campylobacteriosis. Brandmoore Farm distributes raw milk from its retail store located in Rollinsford, NH, as well as at Heron Pond Farm in South Hampton, NH and Dog Rose Farm in Lee, NH. Customers who still have Brandmoore Farms raw milk are advised not to drink it and to dispose of the product. Anyone symptomatic should be evaluated by a medical provider, tested, and treated as appropriate.

Although multiple Maine health care facilities have reported influenza-positive antigen results in recent weeks, this is the first PCR-confirmed case. The individual is an adult who was not hospitalized, was unvaccinated, and had no recent travel history.
It is not too late to vaccinate patients against influenza. Influenza vaccination can flatten the curve of influenza illnesses, and it also can help save medical resources for care of patients with COVID-19. Though influenza activity is currently lower than usual for this time of year, it may increase in the coming months. The 2020-2021 quadrivalent influenza vaccine contains components of both A subtypes (H1 and H3) as well as two B lineages (Yamagata and Victoria).

| Nationwide distribution of the first COVID-19 vaccine started December 14, 2020. U.S. CDC has since received reports that some people have experienced severe allergic reactions -- also known as anaphylaxis -- after receiving a COVID-19 vaccine. An allergic reaction is considered severe when a person needs to be treated with epinephrine or an EpiPen or if they must go to a hospital for emergent care.
On Tuesday, December 22, 2020, Maine Medical Center reported an instance of a severe allergic reaction in an individual who had just received the Pfizer-BioNTech COVID-19 vaccine. The individual's past medical history was significant for severe allergic reactions and eosinophilic asthma. The individual experienced nausea, diaphoresis, and a dry cough that progressed to shortness of breath. The individual received epinephrine, was transported to the Maine Medical Center ED for monitoring, and is doing well.

| Maine CDC has recently received an increase in reported positive influenza antigen tests. Some specimens have been sent to Maine's Health and Environmental Testing Laboratory (HETL) for further analysis, but none have been confirmed.
This is a reminder that providers are asked to send their first ten positive influenza specimens to HETL for confirmation and subtyping. This helps to determine where and which type of influenza is circulating in Maine. Instructions on submitting specimens for influenza testing can be found at: https://www.maine.gov/dhhs/mecdc/public-health-systems/health-and-environmental-testing/micro/submitting-samples.shtml.
Influenza-related hospitalizations, influenza-like illness outbreaks, and influenza-associated pediatric deaths are required to be reported to Maine CDC. Though all other cases of influenza are not required to be reported, Maine CDC does appreciate reports of these as well.
The best way to prevent influenza is by getting vaccinated. Maine CDC and national authorities recommend all individuals older than 6 months be immunized, even if they were vaccinated for influenza last season. It is not too late to get vaccinated.

| On December 2, 2020, the U.S. Centers for Disease Control and Prevention ("CDC") released a Scientific Brief on Options to Reduce Quarantine for Contacts of Persons with SARS-CoV-2 Infection Using Symptom Monitoring and Diagnostic Testing, based on a review of new epidemiological and modeling data.
As noted in this Scientific Brief, local public health authorities determine and establish the quarantine options for their jurisdictions. Based on recent modeling and local circumstances and resources, U.S. CDC has provided data on options to shorten the previous 14-day quarantine period. Considering these data, Maine CDC is changing the quarantine period for individuals known to be close contacts of cases of COVID-19 to 10 days. It is important to note that a shorter quarantine period carries a risk that an exposed individual could become positive and potentially transmit COVID-19 to others after quarantine.

| The purpose of this health advisory is to alert clinicians to the potential for human arboviral disease activity in Maine as summer progresses and to consider testing for arboviral disease in patients presenting with unexplained encephalitis, meningitis or high fever (100.4F or 38C) during the summer and fall when mosquitoes are most active.
Arboviral diseases, including Eastern equine encephalitis (EEE), Jamestown Canyon virus (JCV), and West Nile virus (WNV), are serious infections that are transmitted by the bite of an infected mosquito. Maine reported no cases of locally acquired mosquito-borne infection in residents in 2019. Additionally, Powassan virus is an arboviral disease transmitted by the bite of an infected tick. Maine identified two cases of Powassan virus disease in residents during 2019. Although rare, these diseases have potentially severe and even fatal consequences for those who contract them.

| Maine has seen an increase in hepatitis A cases in Penobscot, Somerset, and York counties over the past four months, with the number of reported cases climbing from zero in January and February to 13 in Penobscot, 7 in Somerset, and 6 in York counties in March through today. Twenty-one of the 26 cases had risk factors of injection drug use or housing insecurity.
Historically Maine had 7 to 10 cases of hepatitis A per year over the past decade. In 2019, Maine CDC identified 45 cases. This increase was driven by a restaurant-associated outbreak and cases related to injection drug use or homelessness. Since January 1, 2020, Maine CDC has identified 39 cases of hepatitis A. Recent case investigations, however, have not identified a source of the infections. The increase of hepatitis A in Maine mirrors an increase of cases seen across the country.

| On March 25, 2020, Maine met U.S. CDC's criteria for a Moderate level of community transmission for coronavirus disease 2019 (COVID-19). Since then Maine's testing capacity has been inhibited by the limited national supply of laboratory materials and testing equipment. To preserve specimen collection and testing supplies for patients who may develop severe COVID-19 illness, Maine CDCs Health and Environmental Testing Laboratory (HETL) has, until now, had to prioritize testing for individuals in high-risk categories.
Maine CDC has expanded its capacity for COVID-19 testing. This expansion results largely from a partnership with IDEXX (Westbrook, Maine) to use the OPTI SARS-CoV-2 RNA PCR Test Kit, which recently received US FDA Emergency Use Authorization. The test kit is based on real-time reverse transcription polymerase chain reaction (RT-PCR), which provides detection of the viral RNA in the sample.

| US CDC's guidelines on Implementation of Mitigation Strategies for Communities with Local COVID-19 Transmission define Moderate community transmission as, "Widespread and/or sustained transmission with high likelihood or confirmed exposure within communal settings with potential for rapid increase in suspected cases." According to US CDC, at that level and when testing capacity is limited, public health control activities may require prioritization of testing to high-risk individuals.
Maine now meets US CDCs criteria for a Moderate level of community transmission. At present, a limited national supply of laboratory materials inhibits Maines testing capacity. Maine may also need to limit testing if such shortages continue. Therefore, consistent with US CDC guidelines, Maine is now creating a prioritization system to test to individuals in high-risk categories. |

| As of March 9, 2020, U.S. states have reported over 500 cases of the novel coronavirus disease (COVID-19). Widespread sustained transmission has also been reported in China, Iran, Italy, and South Korea. Community spread has been reported in several other countries, including parts of the U.S. (California, Oregon, Washington). Community spread in Washington state led to the first death in the U.S. from COVID-19, the first reported case of COVID-19 in a health care worker, and the first outbreak in a long-term care facility.
Widespread transmission of COVID-19 in the U.S. may occur, including within Maine. Such transmission could mean large numbers of patients needing medical care at the same time, stressing health care providers and hospitals/other health care facilities. Critical systems, including emergency medical services, are likely to be affected, and should plan accordingly. Various degrees of social distancing may be required, which could impact daily activities and disrupt scheduled events.
There are no confirmed cases of COVID-19 in Maine at this time. Testing for COVID-19 is available at Maine's Health and Environmental Testing Laboratory. Health care workers caring for patients with COVID-19, close contacts of persons with COVID-19, and travelers returning from affected locations where community spread is occurring are at higher risk. The situation is rapidly evolving. For updates on the situation in Maine, visit https://www.maine.gov/dhhs/mecdc/infectious-disease/epi/airborne/coronavirus.shtml
The clinical spectrum of COVID-19 disease is not fully known, but reported illnesses have ranged from mild to severe. Available information suggests most patients with COVID-19 have mild illness, with severe illness occurring in only 15-20% of patients. Most patients with confirmed COVID-19 have developed fever and/or symptoms of acute respiratory illness (e.g., cough, dyspnea). Risk factors for serious disease associated with COVID-19 include older age and co-morbidities (e.g., heart disease, lung disease, and diabetes). No vaccine to prevent COVID-19 is currently available, nor are there FDA-approved medications for treatment of COVID-19. |

| In 2019, Maine saw a nearly five-fold increase in hepatitis A cases over the five-year average number of cases, increasing from 9 in 2018 to 45 in 2019. A quarter of the cases in 2019 had risk factors such as injection drug use or homelessness.
Maine CDC recommends that healthcare providers and facilities that provide services to at-risk populations obtain hepatitis A vaccine and offer vaccination to their clients to prevent further spread of hepatitis A.
- Screen patients for risk factors (e.g., drug use, homelessness, incarceration, MSM, and chronic liver disease).
- Recommend and administer hepatitis A vaccine to at-risk patients, regardless of the original presenting complaint or the type of clinical facility. In particular, the emergency department may be an individual's only interaction with the healthcare system and is an important opportunity for prevention.
- Record immunizations in the state immunization information system (registry).
- Consider hepatitis A as a diagnosis in anyone with jaundice, elevated liver enzymes, or clinically compatible symptoms. Order an acute hepatitis panel to include hepatitis A IgM on these patients.
Rapidly report all persons diagnosed with hepatitis A to the health department to ensure timely case investigation and follow-up of contacts. |

| Influenza activity in Maine is now widespread with providers reporting laboratory-confirmed influenza in all sixteen counties. Maine's Health and Environmental Testing Laboratory (HETL) confirmed influenza A/pH1N1, influenza A/H3, influenza B/Victoria, and influenza B/Yamagata are all circulating in Maine. Maine CDC has followed up on nine (9) outbreaks of influenza as of Tuesday, January 7, 2020.
With increased influenza activity, it is not too late to get vaccinated. Influenza vaccination is the best way to prevent illness. Vaccination is strongly encouraged throughout the season and is still widely available. |

| Disease Reporting Form |
| The purpose of this health advisory is to inform clinicians that, effective immediately, and pursuant to 22 M.R.S. 802(1)(B), pulmonary disease associated with e-cigarette use is now temporarily added to the list of Notifiable Conditions that are required to be reported to Maine CDC.
Summary: There has been an increase in the number of cases of significant lung illness related to e-cigarette use in Maine. As of Wednesday, October 2, four additional cases of lung illness related to e-cigarette use have been confirmed, bringing Maine's total to five cases. No deaths from this illness have been reported in Maine.
Recommendations: Consider e-cigarette-associated illness with patients who present with respiratory illness of unclear etiology and who have vaped or dabbed within the past 90 days. Clinicians should ask about and document extent of use, type of instrument used, type of vaping liquid used (i.e. nicotine, THC), place of purchase, and if the patient still has the vaping liquid they used. Clinicians should also complete a respiratory viral panel and test for influenza to rule out a possible viral cause of illness.
Reporting: Clinicians should report cases with onset on or after May 1, 2019, that meet the criteria of (1) significant respiratory illness of unclear etiology and (2) a history of vaping. All suspect cases should be reported by phone to Maine CDCs 24/7 disease reporting and consultation line at 1-800-821-5821 or by fax to 1-800-293-7534 using the Disease Reporting Form (attached).
Attention: On October 9, 2019, Maine CDC will be hosting a live webinar to discuss pulmonary illness associated with e-cigarette use. More information to follow.

| Influenza has officially arrived in Maine. Multiple Maine facilities reported influenza positive lab results in the last week, including a PCR confirmed case, which tested positive for influenza A and was typed at Maine's Health and Environmental Testing Lab (HETL) as influenza A/H3. This individual is an adult who was not hospitalized, was unvaccinated, and had recent travel history.
The 2019-2020 influenza season officially begins on September 29, 2019. Individuals should NOT wait to get vaccinated as influenza is already present in the state. Both Influenza A and B strains are currently circulating nationally. The 2019-2020 quadrivalent influenza vaccine contains components of both A strains (H1 and H3) as well as two B strains (Yamagata and Victoria). Quadrivalent vaccine is recommended for optimal protection, however if only trivalent vaccine is available the recommendation is not to wait and obtain the vaccine as soon as possible.

| The purpose of this health advisory is to alert clinicians to the first case in Maine of severe pulmonary disease linked to e-cigarette product use, or "vaping".
Clinicians should consider vaping-associated pulmonary illness in the evaluation of patients with significant respiratory illness and a history of vaping. Patients presenting with significant respiratory illness of unclear etiology should be asked about their use of vaping products. For patients who have used vaping products, clinicians should ask about the extent of use, the type of instrument used, the type of vaping liquid used, and the place of purchase. Patients should also be asked if they still have the vaping liquid they used. If so, Maine CDC can assist with arranging laboratory testing of the liquid.
Reporting: Maine CDC asks that clinicians report cases that meet the criteria of (1) significant respiratory illness of unclear etiology and (2) a history of vaping. All suspect cases should be reported by phone to Maine CDC's 24/7 disease reporting and consultation line at 1-800-821-5821 or by fax to 1-800-293-7534 using the Disease Reporting Form. |

| The purpose of this health advisory is to alert clinicians to the potential for human Eastern Equine Encephalitis (EEE) disease activity in Maine and to consider testing for EEE in patients presenting with unexplained encephalitis, meningitis or high fever (100.4F or 38C) during the summer and early fall.
Maine Department of Agriculture, Conservation, and Forestry notified Maine CDC of a case of Eastern Equine Encephalitis (EEE) in a horse from York County late Friday August 30th. The Animal Health Diagnostic Center at Cornell University in New York confirmed the EEE result in this horse. Maine has not detected EEE to date in mosquito collections. However, public health officials in other Northeast states have seen significant increases in EEE activity this year. Massachusetts has reported four human cases and one human death, as well as four animal deaths from EEE. New Hampshire has reported one animal death from EEE. Maine has not identified a human case of EEE since 2015.
EEE is a rare, but potentially fatal arboviral disease. It is the most severe arboviral infection found in the United States. EEE virus is transmitted to humans through the bite of an infected mosquito. Signs and symptoms can include fever, headache, myalgias, vomiting, weakness, confusion, seizures, and memory loss. In more serious cases, the illness may progress to encephalitis, coma, and death. The case-fatality rate for infected individuals is approximately 33% and up to 50% for those who show symptoms. Most survivors are left with significant and long-term brain damage. Symptoms can begin anytime from four to ten days after the mosquito bite, and usually last one to two weeks. It is possible some people will not show any signs of EEE illness. There is no specific treatment, but people with severe EEE illness often need to be hospitalized.

| In an ongoing effort to provide the most up-to-date information on respiratory illnesses related to e-cigarette use, the Maine Center for Disease Control and Prevention is sharing this advisory from the federal Centers for Disease Control and Prevention.
There have been no confirmed cases of vaping-related respiratory illness in Maine as of Friday, August 30, 2019. Maine CDC continues to ask that clinicians report cases of severe pulmonary disease of unclear etiology and a history of e-cigarette product use within the past 90 days to Maine CDC's 24/7 disease reporting and consultation line at 1-800-821-5821 or by fax to 1-800-293-7534 using the Disease Reporting Form. |

| The purpose of this health advisory is to alert clinicians to reports of severe pulmonary disease linked to e-cigarette product use, or "vaping".
As of August 15, 2019, 94 possible cases of severe lung illness associated with vaping have been reported in 14 states since June 28, 2019. Clusters are occurring in multiple states, including Wisconsin, Illinois, California, Indiana and Minnesota, primarily among adolescents and young adults. Additional states have alerted federal CDC to possible (not confirmed) cases and investigations into these cases are ongoing. There is no conclusive evidence that an infectious disease is causing the illnesses. While some cases in each of the states are similar and appear to be linked to e-cigarette product use, more information is needed to determine the etiology.
Clinicians should consider vaping-associated pulmonary illness in the evaluation of patients with significant respiratory illness and a history of vaping. Patients presenting with significant respiratory illness of unclear etiology should be asked about their use of vaping products. For patients who have used vaping products, clinicians should ask about the extent of use, the type of instrument used, the type of vaping liquid used, and the place of purchase.
It is not yet known if similar cases are occurring in Maine.

| Maine CDC is aware of cases of varicella (chickenpox) in individuals who are staying at the Portland Expo Center. Varicella is a contagious viral disease that can spread easily to individuals who have not had varicella and have not gotten the varicella vaccine. There are several diseases that can cause a febrile rash in children, so Maine CDC encourages laboratory testing when assessing patients when possible. If diagnosed with varicella, patients may return to their congregate living setting if clinically stable and indicated by a provider. Individuals staying at the Portland Expo are already considered exposed. Providers should encourage patients to practice good hand and respiratory hygiene and stay away from non-immune individuals as much as possible. |

| The purpose of this health advisory is to alert clinicians to the potential for human Powassan encephalitis disease activity in Maine and to consider testing for Powassan in patients presenting with unexplained encephalitis, meningitis or high fever (100.4F or 38C) during the summer and early fall.
Maine CDC was notified of a human case of Powassan encephalitis (POW) in a Maine resident who resides in southern Maine. The individual was symptomatic in late June and hospitalized. CDC Fort Collins confirmed the Powassan result in this individual.
Powassan virus is transmitted to humans through the bite of an infected Ixodes tick. Signs and symptoms can include fever, headache, vomiting, weakness, confusion, seizures, and memory loss. Long-term neurologic problems may occur. Symptoms can begin anytime from one week to one month after the tick bite. There is no specific treatment, but people with severe Powassan virus illness often need to be hospitalized.

| In the greater Bangor area, Penobscot County, Maine, physicians have reported 6 confirmed cases of legionellosis from November 2018 to the present. This is an increase from the 5-year median of 3.2 cases for Penobscot County. Cases range in age from over 50 to under 85 years old. Maine CDC is actively investigating the cases and has not identified a common exposure among cases.
Health care providers should be aware of this increase in legionellosis cases and consider legionellosis in the differential diagnosis of any pneumonia case. Although urinary antigen assay is an adequate diagnostic test for Legionella, given the recent increase in number of cases, Maine CDC recommends respiratory specimen culture, particularly for patients who live in the greater Bangor area. Culture specimens can detect all species and serogroups of Legionella and may aide in exposure identification. Maine CDC requests Legionella isolates grown from respiratory specimens be sent to the Maine Health and Environmental Testing Laboratory (HETL) for further analysis. |

| The purpose of this health advisory is to alert clinicians to the potential for human arboviral disease activity in Maine and to consider testing for arboviral disease in patients presenting with unexplained encephalitis, meningitis or high fever (100.4F or 38C) during the summer and early fall.
Arboviral diseases, including Eastern equine encephalitis (EEE), Jamestown Canyon virus (JCV), and West Nile virus (WNV), are serious infections that are transmitted by the bite of an infected mosquito. Maine reported a fatal case of JCV infection, a relatively rare arboviral disease carried by mosquitoes, in a resident in 2018. Additionally, Powassan virus is an arboviral disease transmitted by the bite of an infected tick. Maine identified zero cases of Powassan virus disease in residents during 2018. Although rare, these diseases have potentially severe and even fatal consequences for those who contract them. |

| Maine Center for Disease Control and Prevention (Maine CDC) identified additional cases of acute hepatitis A virus infection in Aroostook County. Close contacts at risk are already being notified. The only risk to the public identified by Maine CDC at this time involves a Presque Isle food service worker.
The Presque Isle case served food and drink while infectious on May 26, 2019 and June 2, 2019.
Maine CDC recommends the hepatitis A vaccine as post-exposure prophylaxis to anyone who ate or worked at the Mai Tai Restaurant in Presque Isle, Maine between 11:00am and 4:30pm on June 2, 2019. Exposed persons can receive post-exposure prophylaxis up to 14 days from exposure, after which the treatment is no longer effective. Anyone who visited the restaurant between 11:00am and 4:30pm on May 26, 2019 is outside the window for which prophylaxis is recommended, but they should watch for symptoms and seek medical attention should they develop symptoms.
Health care providers are encouraged to remain vigilant for hepatitis A infection in persons with consistent symptoms. All cases of hepatitis are reportable in Maine. Providers with suspected cases should report them to Maine CDC at 1-800-821-5821. |

| Maine CDC recently received notification of an infant with perinatally acquired HIV infection. The last infant in Maine with HIV infection attributed to perinatal transmission was born in 2019. Perinatal HIV infections are rare, with 21 cases of HIV attributed to perinatal transmission in the U.S. in 2021, the last year for which data are available. Perinatal HIV in the U.S. has fallen by more than 95% since the early 1990s. Perinatal HIV transmission occurs when HIV is passed from a pregnant person to their child during pregnancy, childbirth, or breastfeeding/chestfeeding. Having an undetectable viral load in pregnancy, and throughout the duration of breastfeeding/chestfeeding, lowers the risk of perinatal transmission of HIV to <1%. Most pregnant people living with HIV can have vaginal deliveries: for people with a high viral load (>1,000 copies/mL) near the time of delivery, a scheduled cesarean delivery can reduce the risk of perinatal HIV transmission. |
