A tick bite usually looks like a lump with a small scab on the skin surface at the site of the bite.
Diagnosis of RMSF is almost always made on the basis of the characteristic symptoms, coupled with either a known tick bite (noted by about 60 to 70 percent of patients) or exposure to an area known to harbor ticks.
It is considered a bad prognostic sign to develop symptoms of RMSF within only two to five days of a tick bite.
The most recognizable indicator of Lyme disease is a rash around the site of the tick bite.
