Definition: 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.
Synonym(s): Ebola hemorrhagic fever
