Hemorrhagic Fevers: MedlinePlu

Viral hemorrhagic fevers are a diverse group of animal and human illnesses in which fever and hemorrhage are caused by a viral infection. VHFs may be caused by five distinct families of RNA viruses: the families Filoviridae, Flaviviridae, Rhabdoviridae, and several member families of the Bunyavirales order such as Arenaviridae, and Hantaviridae. All types of VHF are characterized by fever and bleeding disorders and all can progress to high fever, shock and death in many cases. Some of the VHF a Hemorrhagic fever is a very serious complication of viral infection. The condition is characterized by sudden onset of constitutional symptoms that rapidly progress to bleeding diatheses, shock, and organ failure with high mortality. Various RNA viruses may cause hemorrhagic fevers

VHF-endemic areas are found throughout the world, yet traditional diagnosis of VHF has been performed in large reference laboratories centered in Europe and the United States Background: China is a country that is most seriously affected by hemorrhagic fever with renal syndrome (HFRS) with 90% of HFRS cases reported globally. At present, HFRS is getting worse with increasing cases and natural foci in China. Therefore, there is an urgent need for monitoring and predicting HFRS incidence to make the control of HFRS more effective Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic disease transmitted by ticks and characterized by fever and hemorrhage [ 1,2 ].
