Western equine encephalitis virus is an alphavirus that was originally isolated from the brains of horses in an epizootic outbreak in the San Joaquin Valley of California in The virus is found in the western United. “Submergence” of Western equine encephalitis virus: Evidence of positive selection argues against genetic drift and fitness reductions Nicholas A. Bergren, Sherry Haller, Shannan L. Rossi, Robert L. Seymour, Jing Huang, Aaron L. Miller, Richard A. Bowen, Cited by: 3. Western equine encephalitis virus, member of the family Togaviridae, genus Alphavirus. Closely related to eastern and Venezuelan equine encephalitis viruses; Clinical Features: Symptoms range from mild flu-like illness to frank encephalitis, coma and death.   Western equine encephalitis (WEE) is a viral, vector-borne disease that can cause inflammation of the brain. Mosquitoes transmit the virus from birds to horses and humans. There is no cure for WEE, but the prognosis is fair. Vaccination and good vector management practices are important for protecting horses from WEE.

CDC has received reports of 37 western equine encephalitis (WEE) cases among humans and cases among horses in the Plains and Rocky Mountain states thus far this year. This outbreak is the largest in the United States since , when 41 cases among humans were reported. The severity of the disease depends on the individual virus. Infections with Eastern and Venezuelan equine encephalitis are generally severe and can progress to death over a short period of time. West Nile virus and Western equine encephalomyelitis are less severe.   The main legislation covering the control of equine viral encephalomyelitis, is the Infectious Diseases of Horses Order Published 27 September Last updated 18 .

Treatment: There is no cure for Western Equine Encephalitis. Supportive care is administered in horses which show clinical signs. Prognosis: Fair. Mortality rate is % of infected horses. WEE affects horses less severely than EEE. Horses that survive infection cn result with long-term deficits, though it is rare in horses infected with WEE.   Like all alphaviruses, Western equine encephalitis (WEE) has no specific treatment. Management remains focused primarily on supportive and preventive measures. Treatment . NNDSS - Table 1C. Arboviral diseases, neuroinvasive and non-neuroinvasive, St. Louis encephalitis virus disease to Western equine encephalitis virus disease - In this Table, provisional cases* of notifiable diseases are displayed for United States, U.S. territories, and Non-U.S. residents. The book also details important avenues for their control. This book is a special issue of the Archives of Virology, and its pages comprise 21 presentations that were made at a symposium on "Emergence and Control of Zoonotic Viral Encephalitides." The symposium was held April 6–8, , in Les Pensieres, Veyrier du Lac, France.
