Eastern Equine Encephalitis
Eastern Equine Encephalitis (EEE), like all of the equine encephalitis viruses (including West Nile Virus), follows a pattern of residing most of the year in wild bird hosts and becoming a problem only when there is enough circulating virus and enough mosquitoes present to transmit the virus from the wild bird reservoir into horses or people. This pattern is related to rainfall and temperature, which are favorable for the production of mosquitoes throughout most of Virginia. Typical symptoms of encephalitis include staggering, circling, depression, loss of appetite and sometimes fever and blindness.
So far this year we have had one confirmed the first case of Eastern Equine Encephalitis (EEE) in a horse this year.
