West Nile Fever (WNF) is a mosquito-borne viral infection caused by the West Nile virus (WNV), a member of the Flaviviridae family. The virus primarily incubates in a bird-mosquito transmission cycle, with humans and other mammals serving as incidental hosts .
Notable human diseases caused by RNA viruses include influenza, SARS, MERS, COVID-19, Dengue virus, hepatitis C, hepatitis E, West Nile fever, Ebola virus disease, rabies, polio, mumps, and measles. All known RNA viruses, that is viruses that use a homologous RNA-dependent polymerase for replication, are categorized by the International ...
Examples of class II viral fusion proteins include the dengue virus E protein, and the west nile virus E protein. [5] [6] Class III: Structural conformation is a combination of features from Class I and Class II viral membrane fusion proteins. An example of a Class III viral fusion protein is the rabies virus glycoprotein, G. [6]
