Introduction. Scrub typhus (ST) is a febrile illness caused by the Gram-negative coccobacillus bacteria Orientia tsutsugamushi that are transmitted to humans through the bites of infected larval mites known as “chiggers” (belonging to the family Trombiculide).
There are more than 2000 species of trombiculid mites in many genera, but only about 20 species commonly attack people. The family Trombiculidae has a more or less worldwide distribution, but the medically most important species, such as Leptotrombidium deliense, L. akamushi and L. fletcheri, which are vectors of scrub typhus (Orientia tsutsugamushi), are found in Asia, the Pacific regions and ...
Nov 4, 2019 · Scrub typhus is a vector-borne zoonotic disease with the potential of causing life-threatening febrile infection in humans. The disease is caused by a Gram-negative bacterium, Orientia tsutsugamushi, and is transmitted by the larval stage of mites (“chiggers”) in the family Trombiculidae.
scrub typhus, acute infectious disease in humans that is caused by the parasite Orientia 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 O. tsutsugamushi, is primarily a parasite of certain mites, of which two closely related species ...
Key Points. Scrub typhus, endemic in Asia-Pacific, is transmitted by the bite of chiggers (mite larvae). Fever (often accompanied by an eschar at the bite site), chills, severe headache, and generalized lymphadenopathy start suddenly; a rash develops and spreads. Treat with doxycycline, which results in rapid improvement even in severe cases.

Scrub typhus is related to rickettsial diseases and is caused by Orientia tsutsugamushi. It is spread by chiggers (mite larvae). People with scrub typhus have a fever, chills, and a headache, followed by a rash several days later. To diagnose the infection, doctors test a sample of the rash and sometimes do blood tests.
