Resumo: This review will cover zoonotic, encephalitic alphaviruses in the family Togaviridae. Encephalitic alphaviruses, i.e. Western- (WEEV), Eastern- (EEEV), Venezuelan equine encephalitis virus (VEEV) -, more rarely, Ross River virus, Chikungunya virus - Highl-s J virus (HJV), are neuroinvasive - may cause neurological symptoms ranging from mild (e.g., febrile illness) to severe (e.g., encephalitis) in humans - equines. Among the naturally occurring alphaviruses, WEEV, EEEV - VEEV have widespread distributions in North, Central - South America. WEEV has found spanning the U.S. from the mid-West (Michigan - Illinois) to the West coast - extending to Canada with human cases reported in 21 states. EEEV is found along the Gulf (Texas to Florida) - Atlantic Coast (Georgia to New Hampshire), as well as in the mid-West (Wisconsin, Illinois - Michigan) - in Canada, with human cases reported in 19 states. In contrast, transmission of VEEV occurs predominantly in Central - South America. As with their geographical distribution, equine encephalitis viruses differ in their main mosquito vector species - their zoonotic potential.
