Epidemic typhus is spread to people through contact with infected body lice. Though epidemic typhus was responsible for millions of deaths in previous centuries, it is now considered a rare disease.

Oct 23, 2023 · INTRODUCTION. Epidemic typhus is a potentially lethal, louse-borne, exanthematous disease caused by Rickettsia prowazekii. R. prowazekii is one of two members of the typhus group of Rickettsia known to cause human illness; the other member, Rickettsia typhi, causes murine typhus. Scrub typhus is caused by Orientia tsutsugamushi.
Typhus is caused by two types of bacteria: Rickettsia typhi or Rickettsia prowazekii. Rickettsia typhi causes endemic or murine typhus. Endemic typhus is uncommon in the United States. It is usually seen in areas where hygiene is poor, and the temperature is cold. Endemic typhus is sometimes called "jail fever."
Nov 13, 2020 · Rickettsia typhi antigens cross-react with closely related typhus group Rickettsia species (i.e. R. prowazekii). While cross-reactivity among different typhus group species may be more pronounced, cross-reaction with spotted fever group Rickettsia also has been reported. Because of this cross-reactivity, IFA cannot provide species-specific results.
