The Ulster County Department of Health is currently investigating the case, which marks the first case of EEE confirmed in New York state since 2015, health officials said.
"Eastern equine encephalitis is a serious and fatal mosquito-borne disease with no vaccine," New York State Health Commissioner Dr. James McDonald said in a statement. "Even though temperatures are getting cooler, mosquito-borne illnesses are still a risk and New Yorkers must be cautious."
