Figure 1. Geographic distribution of the likely county in Minnesota or Wisconsin in which exposure to the Ehrlichia muris–like (EML) pathogen occurred in relation to the risk for Lyme disease, babesiosis, and anaplasmosis. The risk of tickborne disease is based on county-specific mean annual reported incidence of confirmed Lyme disease and confirmed and probable human anaplasmosis and babesiosis cases in Minnesota and Wisconsin during 2007–2013. Counties with ≤10 cases/100,000 population were classified as low risk; counties with 10–24.9 cases/100,000 population were classified as moderate risk; and counties with >25 cases/100,000 population were classified as high risk.
