Flaviviridae Family Phylogeny
Flavivirus genus (visible version) Primary flavivirus transmission vector is the Culex mosquito General life cycle of genus Flavivirus viruses Flaviviruses are (+) sense RNA viruses with no nucleoinvasive replication processes. Flavivirus Genome and Translated Protein Coding Regions Conserved RNA Structures in general Flavivirus genome *from Annu. Rev. Microbiol. 2002 56:371-402 Flavivirus Nucleocapsid • Map indicates states reporting laboratory-positive West Nile virus infection in birds, mosquitoes, animals, or humans during 2002. West Nile Virus in the United States as of February 25, 2004* • Map indicates human cases (in red) during 2003 until Feb. 25, 2004. • Colorado highest w/ 2477 cases, Nebraska next w/ 1867 cases.

WNV Genome Structure
• The genome is not segmented and consists of a single molecule of linear positive- sense single-stranded RNA. The complete genome is 10488–10976 nucleotides long. The 5'–end of the genome has a cap methylated nucleotide cap. The 3'–terminus has no poly (A) tract, or a poly (A) tract (in case of some strains of tick-borne encephalitis complex of flaviviruses). * Büchen-Osmond, C. (Ed), (2003). 00.026.0.01. Flavivirus.
