The epidemiology, virology, and transmission of West Nile virus (WNV) are reviewed, and the clinical features, diagnosis, and treatment of WNV infection are examined. ⋯ There is no established treatment for WNV infection. Currently, prevention and control are the only measures that help decrease the morbidity and mortality associated with WNV infection. As the number of cases escalates and the geographic distribution of WNV infection widens, the epidemic will continue to pose a major challenge to clinicians in the coming years. There is an urgent need for more research on the pathogenesis and treatment of WNV infection.
