A total of 3,498 specimens representing 22 species were collected. A Systematic Review of Mortality from Untreated Scrub Typhus (Orientia tsutsugamushi). Chigger bite (often painless and unnoticed) 3. Extensive sampling of small mammals was conducted in eight provinces of Thailand between September 9, 1992 and April 29, 2001. [2] [3]Although the disease is similar in presentation to other forms of typhus, its pathogen is no longer included in genus Rickettsia with the typhus bacteria proper, Scrub typhus is a mite-borne infectious disease caused by Orientia tsutsugamushi (previously called Rickettsia tsutsugamushi). Eighty-eight percent (3,089 of 3,498) of the animals were collected from a region in Chiangrai Province, which is commonly recognized as endemic for human scrub typhus. prowazekii requires an arthropod vector to infect the human host. The incubation period is usually 6–21 days. Murine typhus spreads through contact with infected fleas. It is an obligate intracellular parasite of trombiculid mites, in which natural transmission is maintained from the female to its eggs (transovarial transmission) and from the eggs to adults (transstadial transmission). tsutsugamushi is an obligately intracellular bacterium that is maintained in nature transovarially in mites. Its serotypes are very diverse.
