Rift Valley fever (RVF) is a viral disease of humans and livestock that can cause mild to severe symptoms. The mild symptoms may include: fever , muscle pains , and headaches which often last for up to a week.
1956: Cache Valley virus isolated in Culiseta inornata mosquitoes in Utah 1960: La Crosse virus was first recognized in a fatal case of encephalitis in La Crosse, Wisconsin. 1977: Rift Valley Fever virus caused approximately 200,000 cases and 598 deaths in Egypt. 2017: Bunyavirales order is created
Rift Valley fever (RVF) outbreaks affecting humans and livestock occur across sub-Saharan Africa, with outbreaks occurring elsewhere infrequently.Outbreaks usually correspond with the El Niño, associated with increased rainfall and flooding, causing increases in the mosquito population, which act as vector for the virus.

the Rift Valley fever (RVF) virus from the genus Phlebovirus (Phenuiviridae). The family Filoviridae (order Mononegavirales ) includes Ebola virus and Marburg virus . The family Flaviviridae (order Amarillovirales ) includes dengue , yellow fever , and two viruses in the tick-borne encephalitis group that cause VHF: Omsk hemorrhagic fever virus ...
Additionally, the fusion of Rift Valley fever virus (RVFV) in late endosomes is inhibited by the interferon-induced transmembrane proteins 2 and 3 (IFITIM2 and IFITIM3). Third, the viral and endosomal membranes are fused to allow for the release of the viral ribonucleoprotein complexes into the cytoplasm (Also the site of viral transcription ...
2006–2007 East Africa Rift Valley fever outbreak: 2006–2007 East Africa: Rift Valley fever: 394 [246] ... Latin America and the Caribbean: Dengue virus: 7,700 [326]
Phenuiviridae is a family of negative-strand RNA viruses in the order Bunyavirales. [1] Ruminants, camels, humans, and mosquitoes serve as natural hosts.Until 2011, member genus Phlebovirus was the only genus of the family with viruses causing disease in humans (e.g. Rift Valley fever virus) [2] [scientific citation needed] except Dabie bandavirus.
