| nine mile fever | <infectious disease> An acute (abrupt-onset), self-limited febrile illness first reported in 1935 in Queensland, Australia. The Q is said not to be for Queensland, but for query since the cause of the disease was long a query (question mark). It is caused by the bacterium Coxiella burnetii, a rickettsia which mainly afflicts sheep and cattle but can be transmitted to humans who have contact with infected animals. Symptoms resemble those of influenza and include sudden onset of fever, headache, malaise, and pneumonia (interstitial pneumonitis) but no rash. (12 Dec 1998) |

| nodal fever | <dermatology> A disorder characterised by the formation of tender, red nodules on the front of the legs. Erythema nodosum primarily affects women and has been associated with certain infections: coccidiomycosis, fungal infections, tuberculosis, hepatitis B and syphilis. A sensitivity to a particular drug (for example penicillin, progestin, birth control pills) may also manifest this disorder. Other disorders and conditions that have been associated with erythema nodosum include: leukaemia, sarcoidosis, rheumatic fever, ulcerative colitis and pregnancy. (27 Sep 1997) |
| North Queensland tick fever | A mild form of tick-borne typhus with eschar, adenopathy, rash, and fever, caused by Rickettsia australis and thought to be transmitted by the tick, Ixodes holocyclus. (05 Mar 2000) |
| dandy fever | Tropical disease caused by a flavivirus (one of the arboviruses), transmitted by mosquitoes. A more serious complication is dengue shock syndrome, a haemorrhagic fever probably caused by an immune complex hypersensitivity after re exposure. (18 Nov 1997) |

| deer-fly fever | <infectious disease, microbiology> A rare infection of rabbits and rodents caused by the bacteria Francisella tularensis. Francisella tularensis is found in many animals (rabbits, rodents) and may be transmitted by direct contact or via insect bite (ticks and deer-fly). Humans can also contract the illness via the direct contact with the infected animal carcass (break in the skin). The illness is characterised by an ulcerative lesion at the site of the inoculation with regional lymph node swelling, pneumonia, fever, chills, headache, muscle pains and joint stiffness. Risk factors include an exposure to rabbits or recent tick bite. A vaccine is available for high risk workers. Treatment is with streptomycin or tetracycline. Tularaemia is fatal in 5% of untreated cases and in less than 1% of treated cases. Incidence: less than 200 cases per year (USA). Origin: Gr. Haima = blood (18 Jul 2002) |
| dehydration 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) |
| swamp fever | <veterinary> virology> Viral disease of horses caused by the equine infectious anaemia virus (eiav; infectious anaemia virus, equine). It is characterised by intermittent fever, weakness, and anaemia. Chronic infection consists of acute episodes with remissions. (12 Dec 1998) |
| swamp fever virus | <virology> A retrovirus, of the Lentivirinae subfamily, and the cause of equine infectious anaemia. Synonym: swamp fever virus. (05 Mar 2000) |
| dengue fever | <microbiology> 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) and 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. (27 Sep 1997) |

| swine fever | An acute, highly contagious disease affecting swine of all ages and caused by the hog cholera virus. It has a sudden onset with high morbidity and mortality. (12 Dec 1998) |
| swine fever virus | A species of the pestivirus genus causing exceedingly contagious and fatal haemorrhagic disease of swine. (12 Dec 1998) |
| symptomatic fever | Elevation of temperature following an injury. Synonym: symptomatic fever, wound fever. (05 Mar 2000) |
| syphilitic fever | The elevation of temperature often present in the early roseolous stage of secondary syphilis. (05 Mar 2000) |
