Tick Typhus (African)

Case definition: a rickettsial disease (spread usually by tick bites) that has a variable onset but most often marked by sudden headache, chills, prostration, fever and general pains. A maculopapular eruption appears on the 5" — 7th day, initially on the upper trunk followed by a spread to the entire body but usually not to the face, palms or soles. Chancre, local erythema develops on bite site with local lymphadenopathy.
