Maine Gov. Janet Mills on Thursday announced she had tested positive for COVID-19.

Mills, in a statement, said she had no symptoms other than a mild scratchy throat.

Mills has been vaccinated and has received two booster shots, the last of which was on April 8.

Mills, who is tested routinely, last tested negative on Tuesday.

"This is a good reminder that even though we may want to be done with COVID, it’s not necessarily done with us," Mills said. "I’m grateful for the strong protection that the vaccine has provided me, which I believe is one of the reasons why I am still feeling well. I’ll be spending the next few days working remotely, monitoring my symptoms, and fully recovering."

"I look forward to getting back out when I can and enjoying all that a beautiful Maine spring has to offer," she continued. "I hope that all eligible Maine people will get vaccinated if they haven’t already, and get a booster dose as well, so as to stay as safe and healthy as possible."

Mills said she would isolate herself for five days, per the recommendation of the Maine and U.S. CDC.
