The expanding bull's-eye rash usually appears within a week of a tick bite and may be accompanied by fever, headache, muscle and joint aches, and fatigue. The long-term affects of the illness are unclear, but in general the symptoms and aftereffects appear to be less severe than those of Lyme disease. Treatment is typically oral antibiotics, usually doxycyline or amoxicillin. The Lone Star tick aggressively feeds on humans, and despite the name of the disease, the tick is found in most of the NE, SE, and S central United States and in the Midwest S of the Great Lakes. The illness was first reported in the late 1980s in Missouri by Dr. Edwin Masters.
