| haemorrhagic enteritis | A disease of turkeys caused by an adenovirus and characterised by splenomegaly and intestinal haemorrhage. (05 Mar 2000) |
| haemorrhagic exudative erythema | <dermatology> This relatively rare disorder is characterised by skin purpura, joint pains, abdominal pain and renal disease (glomerulonephritis). Although Henoch-Schonlein purpura or anaphylactoid purpura, is thought to be a immune complex mediated disease, its exact cause is unknown. Its typical benign coarse can, however, include renal failure. (27 Sep 1997) |
| haemorrhagic fever | A syndrome that occurs in perhaps 20-40% of infections by a number of different viruses of the families Arenaviridae (Lassa fever, Bolivian haemorrhagic fever, Argentinean haemorrhagic fever), Bunyaviridae (Crimean-Congo haemorrhagic fever), Flaviviridae (Dengue haemorrhagic fever, Omsk haemorrhagic fever), Filoviridae (Ebola fever, Marburg virus disease), etc. Some types of haemorrhagic fever are tick-borne, others mosquito-borne, and some seem to be zoonoses; clinical manifestations are high fever, scattered petechiae, gastrointestinal tract and other organ bleeding, hypotension, and shock; kidney damage may be severe, especially in Korean haemorrhagic fever and neurologic signs may appear, especially in the Argentinean-Bolivian types. Five types of haemorrhagic fever are transmissible person-to-person: Bolivian haemorrhagic fever, Lassa fever, Ebola fever, Marburg virus disease, and Crimean-Congo haemorrhagic fever. See: epidemic haemorrhagic fever. Synonym: Ebola haemorrhagic fever. (05 Mar 2000) |
| haemorrhagic fever, american | Diseases caused by american haemorrhagic fever viruses (tacaribe complex viruses). (12 Dec 1998) |
| haemorrhagic fever, crimean | A severe, often fatal disease in humans caused by the crimean-congo haemorrhagic fever virus (haemorrhagic fever virus, crimean-congo). (12 Dec 1998) |
| haemorrhagic fever, ebola | A highly fatal, acute haemorrhagic fever, clinically very similar to marburg virus disease, caused by the ebola virus, first occurring in the sudan and adjacent northwestern (what was then) zaire. The natural reservoir and mode of transmission of the virus are unknown, but secondary infection is by direct contact with infected blood and other body secretions. (12 Dec 1998) |
| haemorrhagic fever, omsk | Infection with the omsk haemorrhagic fever virus, a flavivirus. (12 Dec 1998) |
| haemorrhagic fevers, viral | A group of viral diseases of diverse aetiology but having many similar clinical characteristics; increased capillary permeability, leukopenia, and thrombocytopenia are common to all. Haemorrhagic fevers are characterised by sudden onset, fever, headache, generalised myalgia, backache, conjunctivitis, and severe prostration, followed by various haemorrhagic symptoms. Haemorrhagic fever with kidney involvement is haemorrhagic fever with renal syndrome. (12 Dec 1998) |
| haemorrhagic fever virus | <virology> Any of many viruses in the families Flaviviridae, Filoviridae and Bunyaviridae that are often spread by rodents and biting insects, these viruses cause diseasescharacterised by fever and bleeding (such as Ebola). (09 Oct 1997) |
| haemorrhagic fever virus, crimean-congo | The type species of nairovirus of the family bunyaviridae isolated from febrile patients in africa. It is primarily transmitted by ticks and causes a severe, often fatal disease in humans. (12 Dec 1998) |
| haemorrhagic fever with renal syndrome | <syndrome> An acute febrile disease occurring predominately in asia. It is characterised by fever, prostration, vomiting, haemorrhagic phenonema, shock, and renal failure. It is caused by any one of several closely related species of the genus hantavirus. The most severe form is caused by hantaan virus whose natural host is the rodent apodemus agrarius. A milder form is caused by seoul virus and related species and transmitted by the rodents rattus rattus and r. Norvegicus. (12 Dec 1998) |
