Rickettsialpox: Report of an Outbreak and a Contemporary Review

Abstract
Rickettsialpox is a mild illness characterized by an initial lesion or eschar at the site of a mite bite followed by fever, headache and a papulovesicular rash. It can be confused with a variety of illnesses including several other rickettsial diseases and chickenpox. Rickettsia akari, the etiologic agent, is a rickettsia belonging to the spotted fever group (SFG) or rickettsial illnesses. In spite of significant serologic cross-reactivity with other SFG agents, there is no convincing evidence of cross-immunity to these agents after recovery from rickettsialpox. Tetracycline is the preferred drug in the treatment of this disease.
