Overview

Top of page

Venezuelan equine encephalitis virus (VEEV) is a mosquito-borne alphavirus capable of causing large outbreaks of encephalitis in humans and equids. VEEV has caused periodic outbreaks of febrile and neurological disease, primarily in Latin America since the 1930s. Many outbreaks have involved tens to hundreds of thousands of equine and human cases, have spread over large geographical regions, and have lasted up to several years (Weaver et al., 2004). VEEV is also a highly developed biological weapon amenable to use in warfare or terrorism (Hawley and Eitzen, 2001; Reichert et al., 2009).

Venezuelan equine encephalitis is on the list of diseases notifiable to the World Organisation for Animal Health (OIE). The distribution section contains data from OIE's WAHID database on disease occurrence. For more information, see the website: www.oie.int.
