Tick and Mosquito Frequently Asked Questions

Maine has high rates of tickborne diseases across the state. Lyme disease, anaplasmosis, and babesiosis are the most reported tickborne diseases in Maine. Mosquito-borne diseases acquired in Maine are rare in humans, but can include Eastern Equine Encephalitis (EEE), West Nile virus, and Jamestown Canyon virus.

Tick and mosquito-borne diseases can range from mild to severe and vary based onthe disease. Flu-like symptoms, especially in the summer months, are a sign of a vectorborne illness and could be caused by a tick or a mosquito. If a person is not treated early for a tick or mosquito-borne disease, symptoms could become more serious.

Maine CDC receives many tick and mosquito-related consults through Maine CDC's Disease Reporting Hotline. The Division of Disease Surveillance also participates in many educational events each year. Many people ask where the Maine CDC gets information, so Maine CDC and its partners, through the Vectorborne Workgroup, developed this messaging. Each section below contains answers to frequently asked questions on each topic.
