The Maine Center for Disease Control says a Waldo County resident has died of Powassan virus after being bitten by an infected deer or woodchuck tick.
The CDC says the resident developed neurologic symptoms and died while in the hospital.
Symptoms of Powassan virus infection include fever, headache, vomiting, confusion or memory loss, and can begin within a month of being bitten by an infected tick.
The CDC says ticks are active now in Maine and residents should avoid wooded areas and tall grass where ticks live, use an EPA approved tick repellent, and do tick checks every day on family members and pets.
