Does Lyme disease occur in the south?: a survey of emerging tick-borne infections in the region.

Lyme disease is the most common arthropod-borne infection in the United States. However, the risk of infection varies widely by geographic region. In the South, Borrelia burgdorferi has been identified in ticks and small mammals, but transmission of the agent to humans has not been documented. The Lyme disease-like disorder reported from the region may have another etiology.
