The animals that can infect by West Nile Virus are mosquito, horses, dogs, cats, bats, chipmunks, skunks, squirrels, and domestic rabbits. Usually humans infected the West Nile Virus from bite by infected mosquito. The Virus infects the mosquito then infects humans.
Image reconstructions and cryoelectron microscopy reveal a 45–50 nm virion covered with a relatively smooth protein surface. This structure is similar to the dengue fever virus; both belong to the genus Flavivirus within the family Flaviviridae.
The genetic material of WNV is a positive-sense, single strand of RNA, which is between 11,000 and 12,000 nucleotides long; these genes encode seven non-structural proteins and three structural proteins. The RNA strand is held within a nucleocapsid formed from 12 kDa protein blocks; the capsid is contained within a host-derived membrane altered by two viral glycoproteins.
