Nipah Virus Encephalitis
A Nipah virus infection is a viral infection caused by the Nipah virus. Symptoms from infection vary from none to fever, cough, headache, shortness of breath, and confusion. This may worsen into a coma over a day or two, and 50 to 75% of those infected die. Complications can include encephalitis, inflammation of the brain and seizures following recovery. The Nipah virus (NiV) is a type of RNA virus in the genus ''Henipavirus''. The virus normally circulates among some fruit bats. It can both spread between people and zoonosis, from other animals to people. Spread typically requires direct contact with an infected source. Diagnosis is based on symptoms and confirmed by laboratory testing. Management is restricted to supportive care; there is neither vaccine nor specific treatment. Preventive measures include avoiding exposure to bats and sick pigs, and not drinking raw date palm sap. As of May 2018 about 700 human cases of Nipah virus were estimated to have occurred, and 50 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henipavirus
''Henipavirus'' is a genus of negative-strand RNA viruses in the family ''Paramyxoviridae'', order ''Mononegavirales'' containing six established species, and numerous others still under study. Henipaviruses are naturally harboured by several species of small mammals, notably Pteropus, pteropid fruit bats (flying foxes), microbats of several species, and shrews. Henipaviruses are characterised by long genomes and a wide host range. Their recent emergence as zoonosis, zoonotic pathogens capable of causing illness and death in domestic animals and humans is a cause of concern. In 2009, RNA sequences of three novel viruses in phylogenetic relationship to known henipaviruses were detected in African straw-colored fruit bats (''Eidolon helvum'') in Ghana. The finding of these novel henipaviruses outside Australia and Asia indicates that the region of potential endemicity of henipaviruses may be worldwide. These African henipaviruses are slowly being characterised. ''Nipah virus, Nipa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
