Information about Eastern Equine Encephalitis (EEE) and mosquito control.
Learn about EEE
Eastern equine encephalitis (EEE) is a rare but serious disease caused by a virus that can affect people of all ages. EEE is generally spread to humans through the bite of a mosquito infected with the virus. EEE can cause severe illness and possibly lead to death in any age group; however, people under age 15 are at particular risk. EEE does not occur every year, but based on mosquito sampling, a high risk of occurrence of human cases currently exists. Learn more about EEE and how to protect yourself and your family in this fact sheet about EEE.
A hard frost has now occurred in all communities across the state. People are no longer at risk of mosquito-borne illness in Massachusetts in 2019.
