An Overview of West Nile Virus Biology Essay
West Nile virus WNV belongs to the family Flaviviridae, genus Flavivirus, a single-stranded positive-sense RNA, and was first discovered in a Ugandan woman. 2. This virus. Introduction. West Nile virus WNV is a neurotropic mosquito-borne virus belonging to the genus Flavivirus and the Japanese encephalitis virus serogroup. The genome is represented by a single-stranded positive-sense RNA molecule encoding a single polyprotein comprising a total of three structural proteins corresponding to the viral, West Nile virus WNV, St. Louis Encephalitis virus SLEV, Eastern and Western Equine Encephalitis viruses EEEV and WEEV, Sindbis virus SINV and Rift Valley fever virus RVFV are substantially transmitted in temperate regions except RVFV, and are transmitted by shared vector species including Cx; West Nile virus is an infectious agent belonging to the virus family Flaviviridae, which is transmitted by arthropod vectors. West Nile virus is a neurotropic flavivirus and is an important causative agent. Introduction. West Nile virus WNV is an infectious virus that lives in birds as native reservoir hosts and infects humans, horses, and other mammals via mosquitoes, which act as vectors. Since WNV infects humans, horses and other mammals through mosquitoes, it belongs to a group of viruses transmitted by arthropods. The virus was discovered when it was first isolated from the blood of a Ugandan resident during an epidemiological survey conducted in the suspected endemic zone. mainly occurs in mosquitoes of the Culex spp. but the virus can also be transmitted by other species, such as Aedes and Anopheles. 12, Introduction. West Nile virus WNV is an arthropod-borne virus, i.e. arbovirus of the Flaviviridae family 1,2. The virus is maintained in nature by a mosquito-bird-mosquito transmission cycle, mainly involving mosquitoes of the Culex species, particularly Cx. pipiens, Cx. tarsalis and Cx. quinque fasciatus 3.4. Birds are the natural West Nile virus WNV Flavivirus Flaviviridae is the cause of the most widespread arthropod-borne viral disease in the world and the largest outbreak of neuroinvasive diseases ever observed. Mosquito-borne outbreaks are influenced by intrinsic, for example, vector and viral genetics, vector and host competence, life history traits of vectors. The paper is about a WNv model of West Nile virus, in which the non-local diffusion characterizes the long-distance movements of birds and mosquitoes, the free limits describe their spread fronts, and the seasonal sequence takes into account the effect of the warm and cold seasons. The goodness of the mathematical model is that West Nile virus WNV is a neurotropic human pathogen. is the causative agent of West Nile fever and encephalitis. WNV was introduced to the Western Hemisphere during World War II. late summer of. The biology of the virus is briefly discussed and a comprehensive overview is provided of recent discoveries on virus transmission, virus acquisition, and human infections and diseases. SUMMARY West Nile virus was introduced into the Western Hemisphere during late summer and is causing a significant problem. West Nile is a neurotropic problem caused by West Nile virus WNV, a neurotropic arbovirus. The natural reservoir and biological vector of the WNV are birds and Culex sp. mosquitoes. The life cycle of West Nile virus involves transmission of the microbe from non-human animals to humans via Aedes, Culex, or Anopheles mosquitoes. The West Nile virus can kill horses, birds, dogs and others,
