COVID-19: Maine Data
Maine CDC updates data daily by 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.
Prior to November 25th, 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conducted routine follow-up calls with every identified case, so the count of people who have completed isolations is no longer updated.
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.

Notes about the data:
- 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.
- Total number of emergency room/urgent care visits reported.
- Percentage of emergency room/urgent care visits for influenza-like illness symptoms or influenza-like illness discharge diagnosis.
- Percentage of emergency room/urgent care visits for COVID-19-like symptoms or COVID-19 discharge diagnosis.
Effective October 1, 2020, Maine CDC will update COVID-19 test result data Monday through Friday of each week. Maine CDC will not update these data on holidays.

Which Counties Have Community Transmission? Maine CDC defines community transmission in Maine counties as follows:
Low (no to minimal) community transmission over the last 28 days:
- If new case rate per 10,000 is less than 8
Moderate community transmission over the last 28 days:
- If new case rate per 10,000 is greater than or equal to 8 but less than 16
High (substantial) community transmission over the last 28 days:
- If new case rate per 10,000 is greater than or equal to 16
Tables showing the 28-day case rates are found under the Additional Data Tables (above), under View Tables of Data for the Previous 14 and 28 Days. The case rates can be downloaded as a PDF file.
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.
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.
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, recoveries, and hospitalizations on the day the event occurred.
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:
- Shortness of breath
- Difficulty breathing
- New loss of taste or smell OR
- At least two of the following symptoms:
- Fever (measured or reported)
- Repeated shaking with chills
- Muscle pain
- Sore throat
- Nausea or vomiting
- 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 are Completed Isolations? Completed isolation means a person has met the released from isolation requirements defined by Federal CDC. The requirements are: at least 1 day (24 hours) have passed since recovery, defined as resolution of fever without the use of fever-reducing medications and improvement in symptoms; and, at least 10 days have passed since symptoms first appeared.
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 Completed Isolations. 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 Completed Isolations 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.
