Typhus covers three distinct diseases caused by different bacteria and spread by different insects. Epidemic typhus is caused by Rickettsia prowazekii and travels through body lice. Scrub typhus stems from Orientia tsutsugamushi carried by chiggers found in vegetation. Murine typhus arises from Rickettsia typhi transmitted by fleas living on rats.
The first reliable description of typhus appeared in 1489 AD during the Spanish siege of Baza against the Moors. During that conflict, Spaniards lost 3,000 men to enemy action but an additional 17,000 died of typhus.
Only a few areas of epidemic typhus exist today with cases reported in Burundi Rwanda Ethiopia Algeria and parts of South and Central America. Except for two cases all instances of epidemic typhus in the United States have occurred east of the Mississippi River.
As of 2025 no vaccine is commercially available but treatment relies on the antibiotic doxycycline. Without treatment death may occur in 10 to 60 percent of people with epidemic typhus.
