hemorrhagic fever


Also found in: Dictionary, Thesaurus, Financial, Acronyms, Encyclopedia, Wikipedia.

hem·or·rhag·ic fe·ver

a syndrome that occurs in perhaps 20-40% of infections by a number of different viruses of the families Arenaviridae (Lassa fever, Bolivian hemorrhagic fever, Argentinean hemorrhagic fever), Bunyaviridae (Crimean-Congo hemorrhagic fever), Flaviviridae (Dengue hemorrhagic fever, Omsk hemorrhagic fever), and Filoviridae (Ebola fever, Marburg virus disease). Some types of hemorrhagic fever are tick borne, others mosquito borne, and some seem to be zoonoses; clinical manifestations include high fever, scattered petechiae, bleeding from gastrointestinal tract and other organs, hypotension, and shock; kidney damage may be severe, especially in Korean hemorrhagic fever and neurologic signs may appear, especially in the Argentinean-Bolivian types. Five types of hemorrhagic fever are transmissible person-to-person: Bolivian hemorrhagic fever, Lassa fever, Ebola fever, Marburg virus disease, and Crimean-Congo hemorrhagic fever.

hemorrhagic fever

n.
Any of a group of viral diseases, including dengue, yellow fever, Ebola, and Lassa fever, that are typically transmitted to humans by arthropods or mammals, especially rodents, and that affect multiple organ systems, causing fever and usually bleeding and leading in severe cases to hypotension, shock, coma, and death. Also called viral hemorrhagic fever.

hemorrhagic fever

a group of viral infections characterized by fever, chills, headache, malaise, and respiratory or GI symptoms, followed by capillary hemorrhages and, in severe infection, by oliguria, kidney failure, hypotension, and possibly death. Many forms of the disease occur in specific geographic areas. See also dengue fever, dengue hemorrhagic fever shock syndrome, Ebola virus disease, Lassa fever, Marburg virus disease.

hem·or·rhag·ic fe·ver

(hem'ŏr-aj'ik fē'vĕr)
An infectious syndrome caused by several different viruses. Some types of hemorrhagic fever are tick borne, others mosquito borne, and some airborne; others are zoonoses; clinical manifestations are high fever, scattered petechiae, bleeding in gastrointestinal tract and other organs, hypotension, and shock; kidney damage may be severe, especially in Korean hemorrhagic fever, and neurologic signs may appear, especially in the Argentine-Bolivian types. Four types of hemorrhagic fever are transmissible person-to-person: Lassa fever, Ebola fever, Marburg virus disease, and Crimean-Congo hemorrhagic fever.
