Which is the most common tick-transmitted disease in Minnesota?

• A. Lyme disease
• B. Rocky Mountain spotted fever
• C. Tularemia
• D. Anaplasmosis

Answer: (A)

The key idea is understanding which tick-borne illness is most common in a specific region and why the local tick species drive that pattern. In Minnesota, the black-legged tick (Ixodes scapularis) is widespread and transmits Borrelia burgdorferi, the bacterium that causes Lyme disease. Because this tick species is abundant and actively transmits Lyme disease more often than others in the state, Lyme disease is the most commonly reported tick-transmitted illness there. Rocky Mountain spotted fever is more typical of southern regions and is much less common in Minnesota. Tularemia is rare in this area, and Anaplasmosis, while present, occurs less frequently than Lyme disease. So the combination of the local tick population and the disease it most efficiently transmits makes Lyme disease the correct choice.
