From its first isolation in Uganda, in 1937, up to date, the West Nile virus (WNV) has become a major cause of disease in both humans and animals. Maintained in nature through an enzootic cycle involving birds and mosquitoes, the WNV is liable to occasional epizootic outbreaks, causing diseases in humans and horses. This virus is widely spread in the world and, although most human infections with WNV are asymptomatic, the disease may progress into a severe neurological disorder, resulting in long-term sequelae or death. This study comprises a literature review on scientific articles discussing the theme of WNV. For that, a search was conducted in the databases PubMed and Scientific Electronic Library Online (SciELO) for articles published between 1998 and 2019, using the following descriptors: "West Nile virus", "epidemiology", and "pathogenesis". From the 293 articles found, 88 were selected for full-text reading after abstract screening, 33 of which remained in the final analysis. To reduce the impact of the disease on public health, authorities must conduct epidemiological surveillance and develop preventive measures.
