| Texas fever | An infectious disease of cattle caused by Babesia species and transmitted by ticks. Synonym: bovine haemoglobinuria, redwater fever, Texas fever, tick fever. (05 Mar 2000) |
|---|---|
| therapeutic fever | Treatment of disease by inducing an artificial fever in the patient. Synonym: therapeutic fever. (05 Mar 2000) |
| thermic fever | A severe and often fatal illness produced by exposure to excessively high temperatures, especially when accompanied by marked exertion. It can manifest by elevated body temperature, lack of sweating, hot dry skin, and neurologic symptoms; unconsciousness, paralysis, headache, vertigo, confusion. In severe cases very high fever, vascular collapse, and coma develop. Synonym: heat apoplexy, heat hyperpyrexia, malignant hyperpyrexia, thermic fever. (05 Mar 2000) |
| thirst fever | An elevation of temperature in infants after reduction of fluid intake, diarrhoea, or vomiting; probably caused by reduced available body water, with reduced heat loss by evaporation; an analogous condition in adults is seen when exertion is continued in the face of dehydration. Synonym: dehydration fever, exsiccation fever, inanition fever. (05 Mar 2000) |
| East Coast fever | A serious disease of cattle in eastern and central Africa, caused by the protozoan Theileria parva and characterised by high fever, swelling of the lymph nodes, and high case fatality; transmitted by Rhipicephalus appendiculatus and other ticks of the genus Rhipicephalus. (05 Mar 2000) |
| ebola haemorrhagic fever | An epidemic viral illness seen in southern Sudan and Zaire, caused by the Ebola virus. The illness is characterised by fever, malaise, muscle aches, respiratory symptoms, diarrhoea, vomiting, epistaxis, haemoptysis, haematemesis, rash, tremors and subconjunctival haemorrhages. Transmitted by close bodily contact with infected individuals (blood, faeces and body fluids). Incubation is-21 days with initial symptoms of fever and headache. There is no specific treatment and death can occur within 10 days. (27 Sep 1997) |
| three-day fever | Influenza-like febrile viral disease caused by several members of the bunyaviridae family and transmitted mostly by the bloodsucking sandfly phlebotomus papatasii. (12 Dec 1998) |
| tick-borne fever | A rickettsial disease of ruminants transmitted by the tick Ixodes ricinus in Europe and Rhipicephalus haemaphysaloides supina in India and characterised by pyrexia, depression, and anorexia. (05 Mar 2000) |
| tick fever | <infectious disease> 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. The disease is characterised by sudden onset of headache, chills and fever which can persist for 2-3 weeks, muscle pain. A characteristic rash appears on the extremities and trunk about the 4th day of illness. The rickettsiae grow within damaged cells lining blood vessels which may become blocked by clots. Blood vessel inflammation (vasculitis) is widespread Early recognition of the condition and prompt antibiotic treatment is important in reducing mortality. Synonym: spotted fever, tick fever, and tick typhus. (25 Jun 1999) |
| Tobia fever | <infectious disease> 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. The disease is characterised by sudden onset of headache, chills and fever which can persist for 2-3 weeks, muscle pain. A characteristic rash appears on the extremities and trunk about the 4th day of illness. The rickettsiae grow within damaged cells lining blood vessels which may become blocked by clots. Blood vessel inflammation (vasculitis) is widespread Early recognition of the condition and prompt antibiotic treatment is important in reducing mortality. Synonym: spotted fever, tick fever, and tick typhus. (25 Jun 1999) |
| elephantoid fever | Lymphangitis and an elevation of temperature marking the beginning of endemic elephantiasis (filariasis). (05 Mar 2000) |
| enteric fever | <disease, microbiology> An infectious febrile illness usually spread by contamination of food, milk or water supplies with Salmonella typhi, either directly by sewage, indirectly by flies or by faulty personal hygiene. There are less than 600 cases per year in the us. Asymptomatic carriers harbor the organism in their gallbladder and excrete it in their stools for years. Average incubation time is 10-14 days. Fever, diarrhoeal stools (often bloody), abdominal pain, malaise and a rose coloured rash on the upper abdomen are seen. Severe cases may progress to delirium and obtundation. Complications include glomerulonephritis. Treatment includes intravenous fluids and antibiotics (chloramphenicol or ampicillin). Vaccines are recommended for travel to endemic areas. (27 Sep 1997) |
| entericoid fever | A fever, neither paratyphoid nor typhoid, resembling the latter. (05 Mar 2000) |
| traumatic fever | Elevation of temperature following an injury. Synonym: symptomatic fever, wound fever. (05 Mar 2000) |
| trench fever | A louse-borne disease first recognised in the trenches of world war i, again a major problem in the military in world war II, seen endemically in mexico, n. Africa, e, europe, and elsewhere. The cause, rochalimaea quintana, is an unusual rickettsia that multiplies in the gut of the body louse. Transmission to people can occur by rubbing infected louse feces into abraded (scuffed) skin or conjunctiva (whites of the eyes). Onset of symptoms is sudden, with high fever, headache, back and leg pain and a fleeting rash. Recovery takes a month or more. Relapses are common. Also called wolhynia fever, shin bone fever, quintan fever, five-day fever, meuse fever, his' disease, his-werner disease, werner-his disease. (12 Dec 1998) |
