Abstract: West Nile virus (WNV), an arthropod-borne virus which belongs to the Flaviviridae family is maintained in an enzootic cycle between mosquitoes and birds, but it can also infect and cause disease in horses and humans. The WNV was originally isolated in 1937 from blood of a febrile woman in the West Nile province of Uganda. Since its introduction into North America in the New York area in 1999, it has spread throughout the western hemisphere. Since 1994, an increasing number of severe outbreaks affecting the central nervous system have occurred among humans. Clinical presentation ranges from asymptomatic (approximately 80% of cases) to symptomatic neurologic disease (meningitis, encephalitis and poliomyelitis-like syndrome) and death (less than 1% of cases).
