| encephalitis viruses, tick-borne | A subgroup of the genus flavivirus that causes encephalitis and haemorrhagic fevers and is found in eastern and western europe and the former soviet union. It is transmitted by tick vectors and there is an associated milk-borne transmission from viraemic cattle, goats, and sheep. (12 Dec 1998) |
| typhus, african tick | One of the tick-borne rickettsial diseases of the eastern hemisphere, similar to rocky mountain spotted fever, but less severe, with fever, a small ulcer (tache noire) at the site of the tick bite, swollen glands nearby (satellite lymphadenopathy), and a red raised (maculopapular) rash.

| typhus, queensland tick | One of the tick-borne rickettsial diseases of the eastern hemisphere, similar to rocky mountain spotted fever, but less severe, with fever, a small ulcer (eschar) at the site of the tick bite, swollen glands nearby (satellite lymphadenopathy), and a red raised (maculopapular) rash.

| typhus, tick | Rocky Mountain spotted fever (RMSF), an acute febrile (feverish) disease initially recognised in the rocky mountain states, caused by rickettsia rickettsii transmitted by hard-shelled (ixodid) ticks. Occurs only in the western hemisphere. Anyone frequenting tick-infested areas is at risk for rmsf. Onset of symptoms is abrupt with headache, high fever, chills, muscle pain. And then a rash.the rickettsiae grow within damaged cells lining blood vessels which may become blocked by clots. Blood vessel inflammation (vasculitis) is widespread early recognition of rmsf and prompt antibiotic treatment is important in reducing mortality. Also called spotted fever and tick fever.
