West Nile virus WNV has an enzootic mosquito-bird-mosquito cycle in nature, Culex sp mosquitoes being the main vectors.

Birds are the main amplifying hosts. Humans and horses are incidental dead-end hosts. It produces a flu-like or a self-limited febrile disease in most humans. It can cause encephalitis, meningitis or meningoencephalitis in cases of neurological disease, having greater incidence and mortality from encephalitis in older people and immune-compromised patients. Outbreaks have been reported in Africa, the Middle-east, Europe and Asia. The public health concern regarding WNV if it becomes introduced into Middle- and South-America will depend upon the interaction of several factors.

The prevailing conditions in Colombia are apt for its spread and development. There are two main hypotheses; the virus could become enzootic and endemic and cause limited human disease, or it could become epidemic and cause annual outbreaks affecting large numbers of humans and animals.

It will depend upon Colombian birds' susceptibility to the virus because of biological differences and intra-specific geographical variations in mosquitoe species' vector competence and the environmental effects on its ability to transmit the virus; such factors are determinant in the primary amplifying cycle.

Hace parte del serocomplejo de la encefalitis japonesa junto con los virus Cacipacora, Koutango, encefalitis japonesa, encefalitis de San Luis, encefalitis Murray Valley, Usuto y Yaounde 1. Las personas recientemente vacunadas o infectadas con otros flavivirus pueden tener anticuerpos IgM que producen reacciones cruzadas con VON.

Las epidemias en Nueva York en y en Israel entre presentaron un gran numero de cuervos y gansos muertos respectivamente 8,38 , en contraste las epidemias por VON en el viejo mundo tuvieron pocos reportes de muertes en aves infectadas cuando se presentaron los casos humanos 1.

Los aislados virales del brote en Nueva York mostraron un Aves de Colombia y VON. En Colombia existen aproximadamente 1 especies de aves pertenecientes a cerca de 80 familias Actualmente 43 especies de mosquitos han sido encontradas positivas para el virus 9. En Europa y Norte America, los vectores principales son Cx. Las primeras epidemias por VON ocurrieron en Israel en , y 1. Brotes recientes. De agosto a octubre de ocurrieron casos confirmados con 33 fatalidades, el virus fue aislado de muestras de suero de 4 pacientes.

Este brote fue muy notable debido a la alta mortalidad en las aves infectadas principalmente cuervos y azulejos. En el Salvador se produjo un brote de encefalitis equina Berrocal y J.
