The rare and deadly mosquito-borne illness known as Eastern equine encephalitis was identified in New York for the first time in over a decade last week and the person who contracted it has since died from the virus, the state’s governor announced Monday, making them the second person to die from the infection this season.

EEE was also detected in Windham, New London, Hartford, and Middlesex county mosquitoes. Connecticut’s Department of Public Health said it has been taking the EEE threat serious

New York Gov. Kathy Hochul has declared the mosquito-borne EEE virus an imminent threat to the public after the death of a person in Ulster County.
