Eastern Equine Encephalitis (EEE) is a preventable, but fatal, disease. Horses (and other equine species) are the most sensitive to the disease, but other domestic animals, including llamas and alpacas and some bird species, can be affected by EEE. Unfortunately, this disease can also affect humans — if they are bitten by mosquitoes that carry the virus. Learn more about the transmission and prevention of EEE in Bulletin #1003, Preventing Eastern Equine Encephalitis (EEE) Virus in Maine.
