| 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. It is transmitted by tick vectors and there is an associated milk-borne transmission from viraemic cattle, goats, and sheep. (12 Dec 1998) |
| 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. (12 Dec 1998) |
| 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.

| absorption fever | An elevation of temperature often occurring, without other untoward symptoms, shortly after childbirth, assumed to be due to absorption of uterine discharges through abrasions of the vaginal wall. (05 Mar 2000) |
| acclimating fever | Elevated temperature with malaise that occurs upon working in a very hot environment. (05 Mar 2000) |
| aden fever | <virology> A tropical disease caused by dengue virus (Arbovirus), that is transmitted by the bite of an infected mosquito of the genus Aedes). Four severity grades of the illness are seen: Grade I: fever and constitutional symptoms. Grade II: grade I plus spontaneous bleeding of skin, gums or gastrointestinal tract. Grade III: grade II plus agitation and circulatory failure. Grade IV: profound shock. Grade I infection is seen most frequently in world travelers, where it is usually self-limited and rarely fatal. The other grades are referred to as dengue haemorrhagic fever and are often fatal. Dengue haemorrhagic fever appears to be an infection by one of the other dengue viruses. Prior immunity to a different dengue virus type appears to be important in the development of the more serious haemorrhagic form. Vaccines are available. Protection from mosquitoes is an important preventive measure. (15 Jan 1998) |
| aestivoautumnal fever | <infectious disease> A tropical parasitic disease caused by one of the genus Plasmodium and carried by infected mosquitoes of the genus Anopheles. This parasite uses red blood cells to complete its reproductive cycle. Common symptoms of an attack include high fever, chills, sweats and body aches. (27 Sep 1997) |
| algid pernicious fever | A pernicious malarial attack in which the patient presents symptoms of collapse and shock. (05 Mar 2000) |
| ardent fever | A term sometimes applied to hyperpyrexia occurring in intermittent malarial fever. Synonym: heat apoplexy. (05 Mar 2000) |
| Argentinean haemorrhagic fever | A form of haemorrhagic fever observed in South America, seemingly transmitted by contact from rodents to man and caused by the Junin virus, a member of the family Arenaviridae. (05 Mar 2000) |
| Argentine haemorrhagic fever virus | A member of the Arenaviridae. (05 Mar 2000) |
| artificial fever | 1. Obsolete synonym for pyrotherapy. 2. Treatment of fever. Synonym: artificial fever, induced fever. Origin: pyreto-+ G. Therapeia, treatment (05 Mar 2000) |
| aseptic fever | Fever accompanied by malaise due to absorption of dead but not infected tissue following an injury. (05 Mar 2000) |
| Assam fever | A chronic disease, occurring in India, Assam, China, the area formerly known as the Mediterranean littoral areas, the Middle East, India, Pakistan, China, South and Central America, Asia, Africa caused by Leishmania donovani and transmitted by the bite of an appropriate species of sandfly of the genus Phlebotomus or Lutzomyia; the organisms grow and multiply in macrophages, eventually causing them to burst and liberate amastigote parasites which then invade other macrophages; proliferation of macrophages in the bone marrow causes crowding out of erythroid and myeloid elements, resulting in leukopenia, and anaemia, splenomegaly, and hepatomegaly which are characteristic, along with enlargement of lymph nodes; fever, fatigue, malaise, and secondary infections also occur; different strains of leishmaniasis donovani occur; leishmaniasis infantum in Eurasia, leishmaniasis chagasi in Latin America. Synonym: Assam fever, black sickness, Burdwan fever, cachectic fever, Dumdum fever, kala azar, tropical splenomegaly. (05 Mar 2000) |
