Overview

Incidence and Prevalence

West Nile virus is widely distributed across Australia, Middle East, Western Russia, Southwestern Asia, Africa and Southern Europe. Since 1999, a series of outbreaks, with virus likely of African origin, have increased the incidence of the disease across the previous countries.[1]

Across the western hemisphere, the virus was discovered in 1999 in new York City. The WNV then spread across the continent to the East cost of the US in 4 years, and to Argentina in 6 years.[2][3]
