EEE in Calhoun County

Eastern Equine Encephalitis (EEE)

EEE is one of the most dangerous mosquito-borne diseases in the United States, with a 33 percent fatality rate in people who become ill. People can be infected with EEE from one bite of a mosquito carrying the virus. Persons younger than age 15 and over age 50 are at greatest risk of severe disease following infection. More than 25 percent of the nation’s EEE cases last year were diagnosed in Michigan. The risk of bites is highest for people who work and play outdoors in affected areas.
