What is the replication mechanism of the west nile virus?

West Nile virus. The virus is transmitted by mosquitos. The mosquitos become infected by feeding on infected birds. You can not contract West Nile virus by kissing or touching another person.
Baltimore Class IV. West nile virus has a (+) sense RNA genome that resembles cellular mrna, but without a poly-a tail. This virus uses the cell's machinery, creating a polyprotein that is cleaved to both structural and non-structural (ns) proteins. One of the ns proteins is a polymerase that is responsible for synthesizing the (-) sense RNA molecule that serves as the template for (+) sense genomic progeny rna.
