Maine Gov. Janet Mills announced Sunday that she has tested positive for COVID-19, the second time in less than a year that the governor has contracted the virus.

In a statement Sunday evening, the governor said she tested positive after experiencing a scratchy throat Sunday morning.

Mills plans to follow Maine and U.S. Centers for Disease Control and Prevention guidelines by isolating for a minimum of five days. That means Mills will not be able to accompany first lady Jill Biden on Wednesday when she visits Southern Maine Community College in South Portland.

“Other than a scratchy throat, I feel fine,” Mills said. “I will work remotely over the next few days, and I look forward to getting back to the office later this week.”

Mills attributes her mild symptoms and prognosis to being fully vaccinated and boosted. The governor has been a staunch supporter of COVID-19 vaccines. She tested positive for COVID in April 2022 but recovered within a matter of days. Mills turned 75 in December.

According to the U.S. CDC, all Maine counties have a low level of community transmission of COVID-19. Maine has the highest percentage of residents age 65 and older with an updated (bivalent) booster. COVID-19 testing and vaccination remain widely available in the state.
