Scrub typhus occurs in the Indian subcontinent, SE Asia, the Far East and parts of the Southwest Pacific. R. tsutsugamushi is present in trombiculid-infested rodents in specialised ecological niches known as mite islands particularly in Southeast Asia and islands of the Western Pacific. Not far from Kuala Lumpur, for example, Leptotrombidium deliensis is found in the forest, and L. akamushi in the grass ('lalang').

Photo 1. Larva of Leptotrombidium. Larval mites transmit the infection from rodent to man when he comes into accidental association with mite infested terrain. The mites act as reservoirs since transovarial transmission of the Rickettsia occurs. (X 125)
