Eastern Equine Encephalitis (EEE)

Eastern Equine Encephalitis (EEE)

Eastern equine encephalitis (EEE) is an extremely rare but serious and often fatal infection that causes encephalitis or inflammation of the brain. It is spread by the bite of a mosquito infected with EEE virus (EEEV). EEEV can also infect a wide range of animals including mammals, birds, reptiles, and amphibians. The spread of EEEV to mammals (including humans and horses) occurs through the bite of infected mosquitoes that feed on both birds and mammals. There are no human vaccine for EEE. Prevention of mosquito bites is the most important way to reduce your risk.
