Rickettsialpox.

Rickettsialpox is a member of the spotted-fever group of the rickettsioses and results from an infection with Rickettsia akari. This microbe is transmitted by the bite of the house-mouse mite Liponyssoides sanguineus. Patents experience fevers, sweats, headaches, and a vesicular eruption over the trunk and extremities. The palms and soles are spared. An eschar results at the spot of the mite bite. Tetracycline is the treatment of choice.
