Reducing deer populations may reduce risk of Lyme disease

Reduced deer populations can lead to a reduction in Lyme disease cases, researchers in Connecticut have found that after a 13-year study was conducted. White-tailed deer serve as the primary host for the adult blacklegged tick (Ixodes scapularis) -- the vector for Lyme disease. The study found that the number of resident-reported cases of Lyme disease per 100 households was strongly correlated to deer density in the community.
