The Maine Center for Disease Control says a laboratory confirmed a case of Influenza A.
There has been no word yet on where the patient lives.
Meanwhile, folks living in the Winthrop area can get some extra protection from the flu on Tuesday.
Maine General Health will hold a flu shot clinic from 2 to 6 pm at the Francis Xavier Church on Lake Street in Winthrop.
Each shot costs $20, and it is covered by Medicare.
Officials say you don’t have to make an appointment to get a shot, but you do have to be at least 18 years old.
