COVID-19: Maine Data

On June 23, 2020, Maine CDC changed how we show the dates of cases, deaths, recoveries, 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 and recoveries occurred. For example, if a person reports on Friday that they recovered Wednesday, we now show this recovery on Wednesday. We do this to give the public a better picture of the spread of COVID-19 in the state.

This means updates on June 24 with data as of June 23 at 11:59 PM will be on trend charts on June 23. With this change, you may see that recoveries are higher for previous days. That is because our knowledge of who is released from isolation becomes better every day, as case investigators follow up with people with COVID-19.

Maine CDC updates data daily at 9:30 AM with COVID-19 case investigation data included as of 11:59 PM the previous day. 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.

*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.

Read Details About the Data  

When are Data Updated? Data are updated daily between 11:30 AM and 12:30 PM with COVID-19 results included as of 11:59 PM the previous day.

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 tested with a SARS CoV-2 PCR test result from any approved lab.

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

  • A close contact identified through an epidemiological investigation of a confirmed case becomes symptomatic OR
  • An individual has a positive SARS-CoV-2 serology test AND
    • Is a close contact of a confirmed case (as identified through an epidemiological investigation) OR
    • Is symptomatic with:
      • A cough and/or shortness of breath or difficulty breathing OR
      • At least two of the following symptoms:
        • Fever
        • Chills
        • Repeated shaking with chills
        • Muscle pain
        • Headache
        • Sore throat
        • New loss of taste or smell

What are Recovered Cases? Recovered means a person has met the released from isolation requirements defined by Federal CDC. The requirements are: at least 3 days (72 hours) have passed since recovery, defined as resolution of fever without the use of fever-reducing medications and improvement in respiratory symptoms (e.g., cough, shortness of breath); and, at least 10 days have passed since symptoms first appeared.

What are Other Cases? Other Cases is the number of cases left over after removing recovered and deaths from the cumulative total.

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 Categories are Mutually Exclusive? The only categories that are mutually exclusive are Deaths and Recovered. Deaths are counted both in Cumulative Confirmed/Probable Cases and Deaths. Hospitalizations are counted in the Cumulative Confirmed/Probable and may also be counted in Deaths or Recovered depending on the outcome of the individual.

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.
