| encephalitis, tick-borne | A disease caused by tick-borne encephalitis virus, a species of flavivirus, and a member of the subgroup encephalitis viruses, tick-borne. Tick-borne encephalitis appears to be a spectrum of disease caused by two related viruses: the european subtype - central european encephalitis virus and the eastern subtype - russian spring-summer encephalitis virus.

| 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.

| 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.
