| red fever | An acute infectious disease with fever, headache, and rash, all quite similar to, but milder than, epidemic typhus, caused by a related microoganism, rickettsia typhi (mooseri), transmitted to humans by rat fleas (xenopsylla cheopis). The animal reservoir includes rats, mice and other rodents. Murine typhus occurs sporadically worldwide but is more prevalent in congested rat-infested urban areas. Also known as endemic typhus, rat-flea typhus; urban typhus of malaya). (12 Dec 1998) |

| parrot fever | <chest medicine, disease> Psittacosis is primarily an infectious disease of birds caused by the bacterium Chlamydia psittaci. Transmission from infected birds results in a relatively rare febrile illness characterised by pneumonia and systemic symptoms. A flu-like illness can also occur. Almost any bird can harbor this bacterium in their excreta, tissues, feathers and secretions, but parrots, parakeets and budgerigars are the most common. Psittacosis is considered an occupational disease of pet shop owners. Psittacosis is almost always transmitted to humans by the respiratory route. Average incubation is 7-14 days. (27 Sep 1997) |
| redwater fever | A highly fatal disease of cattle and occasionally of sheep caused by infection with Clostridium haemolyticum. See: bovine babesiosis (05 Mar 2000) |
| catarrhal fever | Old term for the group of respiratory tract diseases including the common cold, influenza, and lobular and lobar pneumonia. (05 Mar 2000) |
| cat-bite fever | Rat-bite fever, presumably spread from rats to cats and thus to humans. Synonym: cat-bite fever. (05 Mar 2000) |
| catheter fever | An elevation of temperature, usually slight and transitory, following catheterization of the urethra, or the passage of blood clots, gravel, or a calculus. Synonym: catheter fever, urethral fever. (05 Mar 2000) |
| cat-scratch fever | <disease> A self-limiting bacterial infection of the regional lymph nodes (lymphadenitis) caused by afipia felis, a gram-negative bacterium recently identified as bartonella henselae. It usually arises one or more weeks following a feline scratch, with raised inflammatory nodules at the site of the scratch being the primary symptom. It results in tender and enlarged lymph glands above the site of injury. A chronic benign adenopathy, especially in children and young adults, commonly associated with a recent cat scratch or bite and caused by bacteria including Bartonella henselae and Alipia felis; the lymphadenopathy usually resolves spontaneously within a period of several months, but complications involving central nervous system, liver, spleen, lung, and skin have been seen. Synonym: benign inoculation lymphoreticulosis, benign inoculation reticulosis, cat-scratch fever, regional granulomatous lymphadenitis. (05 Mar 2000) |
| glandular fever | <haematology, virology> Self limiting disorder of lymphoid tissue caused by infection with Epstein Barr virus (infectious mononucleosis). Characterised by the appearance of many large lymphoblasts in the circulation. (13 Nov 1997) |
| viral 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) |

| relapsing fever | An acute infection characterised by recurrent episodes of pyrexia alternating with asymptomatic intervals of apparent recovery. This condition has worldwide distribution and is caused by spirochetes of the genus borrelia. (12 Dec 1998) |
| remittent fever | A fever pattern in which temperature varies during each 24 hour period, but never reaches normal. Most fevers are remittent and the pattern is not characteristic of any disease, although in the 19th century it was considered a diagnostic term. (05 Mar 2000) |
| vivax fever | <disease, microbiology> A type of malaria caused by the protozoan Plasmodium vivax, it isthe most common form of the disease, is rarely fatal but is the most difficult to cure, and is characterised by fevers that typically occur every other day. (11 Nov 1997) |
| Mediterranean exanthematous fever | An affection occurring sporadically in the Mediterranean littoral marked by a severe chill with abrupt rise of temperature, pains in the joints, tonsillitis, diarrhoea, vomiting, and, on the third to fifth day, a rash of elevated nonconfluent macules beginning on the thighs and spreading to the entire body; lasts from ten days to two weeks and then disappears by rapid lysis without desquamation; probably caused by Rickettsia conorii, like Boutonneuse fever.
