Information for
Eastern Equine Encephalitis
Eastern equine encephalitis (EEE) is a mosquito-borne viral disease. EEE virus (EEEV) occurs in the eastern half of the United States where it causes disease in humans, horses, and some bird species. Because of the high mortality rate, EEE is regarded as one of the most serious mosquito-borne diseases in the United States. Many persons infected with EEE will have no obvious symptoms. In those persons who do develop illness, symptoms of EEE range from mild-flu like illness to inflammation of the brain, coma and death.
There is no specific treatment for EEE. This disease is best prevented by avoiding exposure to mosquitoes.
Maine has reported two residents with confirmed EEE to date, one in 2014 and one in 2015. One of the cases was fatal.
