What should I do with horses demonstrating signs of a central nervous system (CNS) disturbance or encephalitis?
Horses with signs of a CNS disturbance or encephalitis should be evaluated for arboviral infection. Determine if the horse was appropriately immunized against eastern and western equine encephalitis (EEE and WEE) or WNV. Contact the West Virginia Department of Agriculture (304-558-2214), USDA, or the West Virginia Infectious Disease Epidemiology Program (1-800-423-1271) for information on testing a horse for WNV.
