Social history of viruses of encephalitis, of which 105 were fatal, were recorded. A new paramyxovirus was discovered in a victim's brain; it was named Nipah virus, after the village where he had lived. The infection was caused by a virus from fruit bats, after their colony had been disrupted by deforestation. The bats had moved to trees nearer the pig farm and the pigs caught the virus from their droppings. Several highly lethal viral pathogens are members of the "Filoviridae". Filoviruses are filament-like viruses that cause viral haemorrhagic fever, and include the Ebola and Marburg viruses. The Marburg virus attracted widespread press attention
Bunyamwera virus Bunyamwera virus The Bunyamwera virus (BUNV) is a negative-sense, single-stranded enveloped RNA virus. It is the type species of the "Orthobunyavirus" genus, in the "Bunyavirales" order. Bunyamwera virus can infect both humans and "Aedes aegypti" (yellow fever mosquito). It is named for Bunyamwera, a town in western Uganda, where the type species was isolated in 1943. Reassortant viruses derived from Bunyamwera virus, such as "Ngari virus", which has been associated with large outbreaks of viral haemorrhagic fever in Kenya and Somalia. The genetic structure of "Bunyamwera virus" is typical for "Bunyavirales" viruses, which are a family of enveloped negative-sense, single-stranded
