After infection by tick bite, there is an incubation period of 2–14 days. The abrupt onset of the disease includes severe headache, fever, chills, arthralgia, and myalgia. After 2–3 days of these constitutional symptoms, erythematous macules erupt on the wrists, hands, forearms,legs, and ankles, as seen in these figures. Lesions then spread to the palms and soles and the trunk. The macules originally blanch with pressure but soon become purpuric and even necrotic. The disease causes a severe vasculitis and complications include disseminated intravascular coagulation, hemorrhage into the gastrointestinal and urinary tracts, and cardiovascular collapse.
