COVID-19: Maine Data

Maine's state of civil emergency ended on June 30, 2021. After July 3, 2021, Maine CDC will conduct case investigations and contact tracing Monday through Friday. As a result, COVID-19 case data will be updated by 9:30 AM Tuesday through Saturday. Case data will not be updated Sunday and Monday or on holidays. All data are preliminary and may change as Maine CDC investigates cases. For more information about the data, please see the "Read Details About the Data" section below.

Notes about the data:

  1. Not all labs report results to the Maine CDC electronically. Labs reporting manually report only the positive results and are therefore excluded for purposes of calculating the percent positivity rate. Molecular testing includes PCR, isothermal, and NAAT methods.
  2. Total number of emergency room/urgent care visits reported.
  3. Percentage of emergency room/urgent care visits for influenza-like illness symptoms or influenza-like illness discharge diagnosis.
  4. Percentage of emergency room/urgent care visits for COVID-19-like symptoms or COVID-19 discharge diagnosis.

View Total Number of COVID-19 Vaccine Breakthrough Cases in Maine

COVID-19 cases among individuals who have been fully vaccinated are classified as vaccine breakthrough cases. A person is considered fully vaccinated 14 days after receiving their final dose of the COVID-19 vaccine. This number likely reflects an undercount of the true number of breakthrough cases as not all cases are investigated to determine vaccine status and it takes time to validate vaccine status, delaying cases being included in the count. Vaccine breakthrough cases are expected with any vaccine and the FDA-authorized COVID-19 vaccines are extremely safe and effective.

More information about COVID-19 infections after vaccination can be found on the federal CDC website.

Total Number of Validated Vaccine Breakthrough Cases: 656

Read Details About the Data

When are Data Updated? Case data are updated Tuesday through Saturday. Other data sources may have different update schedules.

On June 23, 2020, Maine CDC changed how we show the dates of cases, deaths, and hospitalizations. We now show events on the day they occurred, instead of the day the event was reported to us. As we investigate cases, we learn things that help our understanding of when events such as hospitalizations occurred. We do this to give the public a better picture of the spread of COVID-19 in the state.

On November 9,2020, Maine CDC changed how we show the dates of cases. Maine CDC shows cases on the date the investigation was opened and deaths and hospitalizations on the day the event occurred.

Prior to November 25th, 2020, Maine CDC attempted multiple follow-up calls with every identified case of COVID-19 in Maine in order to assess whether their isolation period was completed. Since that date, Maine CDC has not conducted routine follow-up calls with every identified case, so the count of people who have completed isolations is far smaller than the actual number. As of March 31, 2021, Maine CDC is no longer reporting completed isolation as part of its daily data update.

Starting December 5th, Maine CDC has focused its efforts to follow up with cases of COVID-19 on cases who are under the age of 19, over the age of 64, or who meet certain other criteria (including being hospitalized, identified as a minority, identified as having a disability, being a health care worker or first responder, living or working in congregate settings, or associated with a school or child care facility). Depending on available resources and case levels, Maine CDC may follow up with other cases who do not meet those criteria.

Who is Included in the Data? Data are about individuals who claim residency in Maine regardless of what state they were tested in, or where they are currently living. For example, an individual who claims residency in Maine but lives in Florida will appear in this data even if they were living in Florida at the time of illness. County listings are by residence of patient, not location of the hospital or testing location.

What are Confirmed Cases? This represents the number of persons in whom SARS-CoV-2 RNA was detected using a molecular amplification test (e.g. PCR) from any approved lab.

What are Probable Cases? There are three ways in which someone can meet the probable case definition:

  • The individual Is a close contact of a confirmed case (as identified through an epidemiological investigation) AND has
    • Severe respiratory illness with either clinical or radiographic evidence of pneumonia OR
    • At least one of the following symptoms:
      • Cough
      • Shortness of breath
      • Difficulty breathing
      • New loss of taste or smell OR
    • At least two of the following symptoms:
      • Fever (measured or reported)
      • Chills
      • Repeated shaking with chills
      • Muscle pain
      • Headache
      • Sore throat
      • Nausea or vomiting
      • Diarrhea
      • Fatigue
      • Congestion or runny nose; OR
  • The person has had SARS-CoV-2 detected using an antigen test on a respiratory specimen; OR
  • The person’s death certificate lists COVID-19 or SARS-CoV-2 as a cause of death or a significant condition contributing to death with no laboratory evidence for SARS-CoV-2.

What is an Indeterminate Test? Indeterminate means that the test did not provide a clear negative or positive result.

What is Included in Deaths?A COVID-19 associated death is defined as a death resulting from an illness that is clinically compatible with COVID-19 that is confirmed by an appropriate laboratory test. There should be no period of complete recovery between the illness and death. It is not necessary that COVID-19 be the primary cause of death.

What are Some Limitations? Confirmed data represent only those individuals with positive test results, which likely under-represents the true number of cases in Maine. For individuals not considered to be at high risk, medical providers were advised to diagnose COVID-19 based on symptoms prior to May 18, 2020. Those diagnoses are not reported. All data are preliminary and may change as Maine CDC investigates confirmed cases.
