scrub typhus

acute infectious disease in humans that is caused by the parasite Rickettsia tsutsugamushi and is transmitted to humans by the bite of certain kinds of trombiculid mites, or chiggers. The causative agent of scrub typhus, the bacterium R. tsutsugamushi, is primarily a parasite of certain mites, of which two closely related species, Leptotrombidium (Trombicula) akamushi and L. deliens, are the carriers of the disease. During their larval stage, these mites acquire the infection from wild rodents or other small animals. The infection is passed to humans when a mite larva bites a person. Scrub typhus occurs in Southeast Asia and its associated archipelagoes and in Japan, in which latter country the disease was first described (1899) and systematically investigated (1906-32). During World War II scrub typhus killed or incapacitated thousands of troops who were stationed in rural or jungle areas in the Pacific theatre
