| typhus, epidemic louse-borne | The classic form of typhus, caused by rickettsia prowazekii, which is transmitted from man to man by the louse pediculus humanus corporis. This disease is characterised by the sudden onset of intense headache, malaise, and generalised myalgia followed by the formation of a macular skin eruption and vascular and neurologic disturbances.

| typhus mitior | A mild or abortive typhus. Murine typhus, a milder form of epidemic typhus caused by Rickettsia typhi and transmitted to humans by rat or mouse fleas. Synonym: Congolian red fever, endemic typhus, flea-borne typhus, red fever, red fever of the Congo. North Queensland tick typhus, typhus caused by Rickettsia australis. (05 Mar 2000) |
| typhus, murine | An acute infectious disease with fever, headache, and rash, all quite similar to, but milder than, epidemic typhus, caused by a related microoganism, rickettsia typhi (mooseri), transmitted to humans by rat fleas (xenopsylla cheopis). The animal reservoir includes rats, mice and other rodents. Murine typhus occurs sporadically worldwide but is more prevalent in congested rat-infested urban areas. Also known as endemic typhus, rat-flea typhus, and urban typhus of malaya. (12 Dec 1998) |

| typhus, scrub | A mite-borne infectious disease caused by a microorganism, rickettsia tsutsugamushi, characteristically with fever, headache, a raised (macular) rash, swollen glands (lymphadenopathy) and a dark crusted ulcer (called an eschar or tache noire) at the site of the chigger (mite larva) bite. This disease occurs in the area bounded by japan, india, and Australia. Known also as tsutsugamushi disease, mite-borne typhus, and tropical typhus. (12 Dec 1998) |
| typhus vaccine | A formaldehyde-inactivated suspension of Rickettsia prowazekii grown in embryonated eggs; effective against louse-borne (epidemic) typhus; primary immunization consists of two subcutaneous injections 4 or more weeks apart; booster doses are required every 6 to 12 months, as long as the possibility of exposure exists. A vaccine containing living rickettsiae of an attenuated strain of R. Prowazekii has also been used. (05 Mar 2000) |
