The diseases are caused by specific types of bacterial infection. [1] Epidemic typhus is caused by Rickettsia prowazekii spread by body lice, scrub typhus is caused by Orientia tsutsugamushi spread by chiggers, and murine typhus is caused by Rickettsia typhi spread by fleas. [1] Vaccines have been developed, but none are commercially available.
