Lyme Disease

Lyme disease is an illness caused by a bacterium, Borrelia burgdorferi, transmitted to humans by a tiny tick named Ixodes scapularis (commonly called the blacklegged or deer tick).  Lyme disease may cause signs and symptoms affecting the skin, nervous system, heart, or joints of an infected person.  More than 20,000 cases of the disease have been reported in Wisconsin residents since surveillance for Lyme disease began in 1980.
