Agriculture & Industries Commissioner John McMillan announces that the first positive case of Eastern Equine Encephalitis has been detected in Alabama. EEE is a mosquito-transmitted disease that is much more severe than West Nile Virus. The mortality rate in horses from West Nile Virus is reported at around 30%, while the rate for Eastern Equine Encephalitis is almost 90%. Commissioner McMillan and State Veterinarian Dr. Tony Frazier recommend vaccinating your horses every six months against both diseases. The public is also advised to make every effort to reduce human exposure to mosquitoes during this time of year. The horse positive for EEE in Alabama was from Escambia County.
