New York's governor declared a deadly mosquito-borne virus an "imminent threat" to public health after a death in the state.

“While we normally see these mosquitoes in two to three counties each year, this year they have been in 15 counties so far, and scattered all over New York State. This life-threatening mosquito-borne disease has no commercially available human vaccine and must be taken seriously.

A New York resident who contracted the first confirmed human case of Eastern equine encephalitis in the state in nearly a decade has died, according to the governor's office.
