Tickborne Infections


When enjoying time outdoors, it is important to be aware of ticks and take steps to protect yourself. View the short video on this page for tips on protecting yourself from Lyme disease. For more information on Lyme disease in your community, check out the Wisconsin Environmental Public Health Tracking Portal.

The Wisconsin Department of Health Services and local health departments investigate several tickborne infections including Lyme disease, babesiosis, ehrlichiosis, anaplasmosis, and spotted fever rickettsiosis. Lyme disease is the highest reported tickborne illness in Wisconsin, but numbers for the other conditions are increasing.
