Scrub typhus of Rickettsiae Infection
Scrub typhus is an acute typhus-like disease of Asia caused by multiple serotypes of R. tsutsugamushi. It is transmitted by the bite of the larvae (chiggers) of certain mites. Primary scrub typhus resembles louse-borne typhus in many ways. However, an eschar frequently develops at the site of the inoculation. Response to chemotherapy is rapid. The mortality of the disease ranges from the very low to very high.
