| 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) |
| 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) |
| desert fever | A disease common in the San Joaquin Valley of California and certain additional areas in the southwestern U.S. As well as the Chaco region of Argentina, caused by inhalation of the arthroconidia of Coccidioides immitis; acute onset of symptoms resemble pneumonia or pulmonary tuberculosis, productive of sputum usually containing spores of the fungus, and accompanied by aches, malaise, severe headache, and occasionally an early erythematous or papular eruption; erythema multiforme or erythema nodosum may appear; the coccidioidin test is positive. Synonym: desert fever, San Joaquin fever, San Joaquin Valley disease, San Joaquin Valley fever, valley fever. (05 Mar 2000) |
| digestive fever | A slight rise of body temperature occurring during the period of digestion. (05 Mar 2000) |
| diphasic milk fever | tick-borne encephalitis (Central European subtype) |
| double quotidian fever | Malaria in which two paroxysms of fever occur daily. (05 Mar 2000) |
| drug fever | Fever resulting from an allergic reaction to a drug that clears rapidly on discontinuation of the drug. (05 Mar 2000) |
| Dumdum 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) |
| Dutton's relapsing fever | African tick-borne relapsing fever caused by Borrelia duttonii and spread by the soft tick, Ornithodoros moubata. Synonym: Dutton's relapsing fever. (05 Mar 2000) |
| icterohemorrhagic fever | Infection with the variety of Leptospira interrogans serotype known as icterohemorrhagiae, characterised by fever, jaundice, haemorrhagic lesions, azotemia, and central nervous system manifestations. Synonym: leptospirosis icterohemorrhagica. (05 Mar 2000) |
| Ilheus fever | A febrile illness caused by the Ilheus virus, an arborvirus (genus Flavivirus), and transmitted by a mosquito. See: Ilheus encephalitis. (05 Mar 2000) |
| inanition 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) |
| Q 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) |
