Updated Guidance for COVID-19: Prioritization of Testing and Discontinuation of Home Isolation

March 19, 2020 Advisory (PDF) 
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.

Updated Guidance for COVID-19 Testing

March 16, 2020 Advisory (PDF) 
On March 15, 2020, the U.S. Centers for Disease Control and Prevention (U.S. CDC) and the U.S. Food and Drug Administration (FDA) issued new guidance for collection, handling, and testing clinical specimens from persons for Coronavirus Disease 2019 (COVID-19). These new guidance can be found at https://www.cdc.gov/coronavirus/2019-ncov/lab/guidelines-clinical-specimens.htm and https://www.fda.gov/medical-devices/emergency-situations-medical-devices/faqs-diagnostic-testing-sars-cov-2. Key Messages: - U.S. CDC is now recommending collecting a single nasopharyngeal (NP) swab in viral transport media. Throat (OP) swabs are no longer required. If both swabs are used, they should be combined at collection in to a single vial. - FDA has expanded options for specimen transport media. - The Maine Health and Environmental Testing Laboratory (HETL) will no longer be running a respiratory viral panel with all submitted COVID-19 specimens.

Actions to Take Now for Community Transmission of COVID-19

March 15, 2020 Advisory (PDF) 
As of March 15, 2020, there are 7 confirmed and 5 presumptive positive COVID-19 cases in Maine. Community transmission is occurring in Cumberland County. The Maine Center for Disease Control and Prevention (Maine CDC) expects to see community transmission in other areas of Maine, possibly in the coming days. Such transmission will likely mean large numbers of patients needing medical care at the same time, stressing health care providers, hospitals, and other health care facilities. Critical systems, including emergency medical services, are likely to be affected, and should plan accordingly. Social distancing strategies should be implemented, even though they may impact daily activities and disrupt scheduled events.

First Presumptive COVID-19 Case in Maine

March 12, 2020 Advisory (PDF) 
On Thursday, March 12, 2020, Maine's Health and Environmental Testing Laboratory (HETL) reported out the first presumptive positive COVID-19 test result on a Maine resident. Currently, all positive COVID-19 results from state public health laboratories are considered presumptive until they are confirmed at the U.S. Center for Disease Control and Prevention (U.S. CDC). Health care providers should immediately notify infection control personnel at their health care facility if they suspect a patient of having COVID-19. Providers and health care facilities do not need to notify Maine CDC if they suspect their patient of having COVID-19, and do not need authorization to send samples to HETL. Providers should work with their health care facilities to determine the best location and method for specimen collection.

COVID-19 Updated U.S. CDC Guidance

March 12, 2020 Advisory (PDF) 
On March 10, 2020 the U.S. Centers for Disease Control and Prevention (U.S. CDC) released the following new or revised guidance in response to concerns around national and local shortages in Personal Protective Equipment (PPE) supplies, particularly N95 respirators: - Infection Prevention and Control - Emergency Medical Services (EMS) - Long-Term Care Facilities Other guidance issued includes - Guidance for Based Precautions and Disposition of Hospitalized Patients - People at risk for serious illness from COVID-19. Maine CDC is also providing additional guidance to providers seeking COVD-19 testing at Maine's Health and Environmental Testing Laboratory (HETL): - Providers no longer need to call Maine CDC for authorization prior to submitting a sample for testing - Nasopharyngeal (NP) and throat (oropharyngeal) swabs no longer need to be sent in separate viral transport media. NP and OP swabs can be submitted in a single container of viral transport media

Preparing for Community Transmission of COVID-19 in Maine

March 9, 2020 Advisory (PDF) 
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.

Updated COVID-19 Testing Criteria

March 5, 2020 Advisory (PDF) 
On Wednesday, March 4, 2020, the U.S. Centers for Disease Control and Prevention (U.S. CDC) expanded the Coronavirus Disease 2019 (COVID-19) testing criteria to a wider group of symptomatic patients. A patient who is suspected of having COVID-19 must wear a surgical mask as soon as they are identified and be evaluated in a private room with the door closed, ideally an airborne infection isolation room if available. Health care personnel entering the room should use standard precautions, contact precautions, airborne precautions, and use eye protection (e.g., goggles or a face shield). If providers suspect their patient of having COVID-19, they should immediately notify their health care facility's infection control personnel and Maine CDC at 1-800-821-5821. In the case of a patient suspected of having COVID-19, specimens must be sent to Maine Health and Environmental Testing Laboratory (HETL). Health care providers should remind all patients being tested for COVID-19 to remain isolated until test results are back and are negative.

Updated COVID-19 Patients Under Investigation (PUI) Criteria

February 28, 2020 Advisory (PDF) 
U.S Centers for Disease Control and Prevention (U.S. CDC) updated the Coronavirus Disease 2019 (COVID-19) criteria for Patients Under Investigation (PUI) on Thursday, February 27, 2020. A person who meets the PUI criteria must wear a surgical mask as soon as they are identified and be evaluated in a private room with the door closed, ideally an airborne infection isolation room if available. Health care personnel entering the room should use standard precautions, contact precautions, airborne precautions, and use eye protection (e.g., goggles or a face shield). If providers suspect a patient meets the PUI criteria, they should immediately notify their healthcare facility's infection control personnel and Maine CDC at 1-800-821-5821. Currently, testing for COVID-19 is not yet available in Maine. In the case of a PUI, specimens must be sent to HETL who will facilitate sending them to U.S. CDC for COVID-19 testing. There are no confirmed cases of COVID-19 in Maine at this time; therefore, the risk of community spread remains low.

Influenza-Associated Pediatric Death

February 19, 2020 Advisory (PDF) 
Maine CDC received notification of an influenza-associated pediatric death on Tuesday, February 18, 2020. The child, a southern Maine resident under 5 years old, was unvaccinated and tested positive for influenza B. This is the first influenza-associated pediatric death in Maine during the 2019-20 influenza season. Influenza activity in Maine remains elevated. Influenza vaccination is strongly encouraged, and vaccine is still widely available. Vaccination can reduce illness and prevent hospitalization and death.

Maine CDC Encourages Providers to Obtain Vaccine and Vaccinate At-Risk Populations for Hepatitis A

February 13, 2020 Advisory (PDF) 
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.

Update and Interim Guidance on Outbreak of 2019 Novel Coronavirus (2019-nCoV)

February 4, 2020 Advisory (PDF) 
The Centers for Disease Control and Prevention (federal CDC) continues to closely monitor an outbreak of respiratory illness caused by a novel coronavirus (2019-nCoV) that was initially detected in Wuhan City, Hubei Province, China in December 2019. This federal CDC Health Alert Network (HAN) Update provides a situational update and interim guidance to state and local health departments that supersedes guidance in federal CDC's HAN 426 distributed on January 17, 2020. - As of February 4, 2020, no cases of 2019-nCoV have been identified in Maine. - If a patient meets the PUI criteria, the provider should contact Maine CDC immediately, by calling 1-800-821-5821, to determine if this patient needs to be considered a PUI for 2019-nCoV and be tested for infection.

Increase in Suspected Unintentional Overdoses in Cumberland County

February 1, 2020 Advisory (PDF) 
On Saturday, February 1st, the Northern New England Poison Control Center notified Maine CDC of ten individuals who potentially overdosed unintentionally over the weekend. All ten individuals received emergency assistance in Cumberland County. Cases were reported from multiple facilities. Some of these individuals may have thought that they were using cocaine, but the cocaine may have been contaminated with opioids. At least one individual indicated they purchased the cocaine from a new dealer. Several individuals were seriously impaired and required naloxone to recover, some needing multiple doses. The intent of this HAN is to alert Emergency Medical Services, health care facilities and providers, and law enforcement to a potentially contaminated product that is leading to severe adverse outcomes.

Updated Definition for Patients Under Investigation (PUI) for 2019 Novel Coronavirus (2019-nCoV)

January 31, 2020 Advisory (PDF) 
Imported cases of 2019-nCoV infection in people have been detected in the U.S. While person-to-person spread among close contacts has been detected with this virus, this virus is NOT currently spreading in the community in the United States. At this time, Maine does not have any confirmed cases and has no patients under investigation (PUI). U.S Centers for Disease Control and Prevention (U.S. CDC) updated the 2019 Novel Coronavirus (2019-nCoV) definition for patients under investigation (PUI) on Friday, January 31, 2020.

Update and Guidance on Outbreak of 2019 Novel Coronavirus (2019-nCoV)

January 21, 2020 Advisory (PDF) 
The Centers for Disease Control and Prevention (CDC) continues to closely monitor an outbreak of a 2019 novel coronavirus (2019-nCoV) in Wuhan City, Hubei Province, China that began in December 2019. CDC has established an Incident Management System to coordinate a domestic and international public health response. Coronaviruses are a large family of viruses. Some cause illness in people; numerous other coronaviruses circulate among animals, including camels, cats, and bats. Rarely, animal coronaviruses can evolve and infect people and then spread between people such as has been seen with Middle Eastern Respiratory Syndrome Coronavirus (MERS-CoV) (https://www.cdc.gov/coronavirus/mers/index.html) and Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) (https://www.cdc.gov/sars/index.html).

Lead Poisonings Requiring Medical Chelation Treatment

January 16, 2020 Advisory (PDF) 
Between July and December 2019, four children ages 12 to 24 months were identified with blood lead levels ranging from 45 to 57 mcg/dL. Blood lead levels of 45 mcg/dL or higher are typically treated with medical chelation therapy to reduce blood lead levels. These are the first chelation cases identified in Maine since 2016. The children resided in Androscoggin, Cumberland, and York counties.

Widespread Influenza Activity in Maine

January 7, 2020 Advisory (PDF) 
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.

Vaping-associated Pulmonary Illness - Reporting Now Required

October 3, 2019 Advisory (PDF)  | 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 Arrives in Maine

September 27, 2019 Advisory (PDF) 
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.

Maine Reports a Case of Lung Illness Related to E-Cigarette Use

September 20, 2019 Advisory (PDF) 
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.

Eastern Equine Encephalitis Positive Horse

September 3, 2019 Advisory (PDF) 
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.

Severe Pulmonary Disease Associated with Using E-Cigarette Products

August 30, 2019 Advisory (PDF) 
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.

Vaping-associated Pulmonary Illness - Call for Cases

August 21, 2019 Advisory (PDF) 
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.

Cases of Varicella (Chickenpox) Associated with the Portland Expo Center

August 3, 2019 Advisory (PDF) 
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.

Human Powassan Case

July 24, 2019 Advisory (PDF) 
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.

Increase in Legionellosis Cases - Greater Bangor Area, Penobscot County

July 12, 2019 Advisory (PDF) 
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.

Maine CDC Update on Portland Expo Operations

July 3, 2019  
Maine CDC continues to support the City of Portland in connection with asylum seekers residing at The Expo. The response has involved conducting health screenings, providing vaccinations, and offering assistance through the Women, Infants and Children (WIC) program.

Human Arbovirus Information for Healthcare Providers in Maine

July 2, 2019 Advisory (PDF) 
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.
