Figure 5. Probable counties of patient exposure to ticks in Minnesota and Wisconsin in relation to risk of diseases transmitted by I scapularis.

Figure 5

I scapularis-transmitted diseases in the figure were Lyme borreliosis, babesiosis, and anaplasmosis. The county of residence for each patient (indicated with a circle) is deemed a county of potential exposure except for the patient from North Dakota, whose county of residence is not shown. Some patients had probable exposures in one or more county in addition to their county of residence (indicated with a triangle). The risk of disease transmitted by I scapularis is based on county-specific mean annual reported incidence of confirmed Lyme borreliosis and confirmed and probable human anaplasmosis and babesiosis in Minnesota and Wisconsin in 2007–13. Counties with 10·0 or fewer cases per 100 000 people were classified as low risk, counties with 10·1–24·9 cases per 100 000 people were classified as moderate risk, and counties with 25·0 or more cases per 100 000 people were classified as high risk.
