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
Oropouche virus towards Panama, Acre, and Maranhão. From Maranhão, the genotype progressed towards Minas Gerais. Finally, genotype IV emerged from the city of Manaus and Amazonas. OROV has been used extensively in testing with Hela cells to study the mechanisms of apoptosis induced by the virus. It was found that OROV causes apoptosis by DNA fragmentation. In UV-inactivated OROV, virus-receptor binding was not enough and that viral uncoating and replication were needed to induce apoptosis. Oropouche virus The Oropouche virus (OROV) is one of the most common orthobunyaviruses. When OROV infects humans, it causes a rapid fever illness called Oropouche fever. OROV
