Tickborne Diseasestick

Maine has high rates of tickborne diseases. Lyme disease, anaplasmosis, and babesiosis are the most commonly reported tickborne diseases in Maine. Tracking the spread of tickborne diseases allows communities, state officials, and healthcare providers to prepare strategies to prevent the spread of these diseases. This data helps individuals educate residents about the need for early detection and treatment to prevent the progression to the debilitating late-stage of these diseases.
