Recommendations for COVID Positive Cases

Maine CDC created informational packets with recommendations for certain groups:

Long-Term Health Effects of COVID-19

The Maine Center for Disease Control and Prevention (Maine CDC) announced on April 23, 2021, that it will begin a survey of Maine residents who had COVID-19 to study the long-term physical and mental health consequences of COVID-19. The survey has been designed by the epidemiologists at Maine CDC and at the U.S. Centers for Disease Control and Prevention.

Between March 2020 and August 31, 2021, Maine CDC identified more than 75,000 cases and 900 deaths related to COVID-19. Recent studies suggest that people who had COVID-19 in the past may suffer from symptoms for weeks or months after their diagnosis, including those who had no symptoms or who had mild symptoms at the time of their diagnosis. Often referred to as “Long COVID”, these symptoms can include fatigue, breathlessness on exertion, muscle weakness, brain fog, altered taste or smell, headaches, gastrointestinal symptoms, anxiety, and depression. People from all age groups may be affected. Epidemiologists from Maine CDC will conduct this survey to understand how people recover from COVID-19 since the diagnosis. In order to best understand recovery from COVID-19, all those who receive an invitation to participate in the survey are encouraged to reply, regardless of their COVID-19 symptoms.

In May 2021, Maine adults who tested positive for COVID-19 in 2020 and provided their cell phone numbers at the time of COVID-19 testing received a text message with a link to the survey to take online on their cell phones. Maine CDC will now extend the invitation and send out survey links to those Maine adults who tested positive for COVID-19 between January 1, 2021 and August 31, 2021. The survey will take approximately 10-15 minutes to complete and will be available in English and Spanish. Participation in the survey is voluntary. All data collected during this survey will be stored on secure servers at the Maine Department of Health and Human Services. No individual will be identified and results from the survey will be disseminated to the Maine public and health care professionals in an aggregated and de-identified form. The survey has been approved by the Institutional Review Board of the U.S. Centers for Disease Control and Prevention. Results from this survey will help Maine CDC better plan for healthcare needs of people recovering from COVID-19 and create awareness about the possibility of long-term health effects of COVID-19.

For additional questions regarding this study, you can email If you were diagnosed with COVID-19 on or before August 31, 2021, do not receive a text message with the survey link, and wish to participate in the survey, please send an email to This survey will be accepting responses until October 31, 2021.
