Lyme Disease Directory
Lyme disease is a bacterial infection transmitted by deer ticks infected with the Borrelia burgdorferi bacteria. Named after the town in Connecticut where the disease was first discovered, Lyme disease causes a peculiar rash and arthritis symptoms. Lyme disease has been reported in nearly all U.S. states, although most cases are concentrated in the coastal northeast, Mid-Atlantic States, Wisconsin, Minnesota, and northern California. In addition to causing arthritis, Lyme disease can also cause heart, brain, and nerve problems.
