<unk> , also known as<unk>  fever, is a group of infectious diseases that include epidemic<unk> , scrub<unk> , and murine<unk> . Common symptoms include fever, headache, and a rash. Typically these begin one to two weeks after exposure. The diseases are caused by specific types of bacterial infection. Epidemic<unk>  is due to Rickettsia prowazekii spread by body lice, scrub<unk>  is due to Orientia tsutsugamushi spread by chiggers, and murine<unk>  is due to Rickettsia typhi spread by fleas. Vaccines have been developed, but none are commercially available. Prevention is achieved by reducing exposure to the organisms that spread the disease. Treatment is with the antibiotic doxycycline. Epidemic<unk>  generally occurs in outbreaks when poor sanitary conditions and crowding are present. While once common, it is now rare. Scrub<unk>  occurs in Southeast Asia, Japan, and northern Australia. Murine<unk>  occurs in tropical and subtropical areas of the world.<unk>  has been described since at least 1528. The name comes from the Greek tûphos () meaning fever or delusion, describing the state of mind of those infected. While "typhoid" means<unk> -like",<unk>  and typhoid fever are distinct diseases caused by different types of bacteria.
