The New York State Department of Health is advising residents to take extra safety precautions when going outside in order to avoid mosquito bites.
These may include the use of repellents and treated clothing, such as pants, boots and socks.
The recommendation comes after two confirmed detections of the deadly Eastern Equine Encephalitis Virus (EEE) in mosquito pools in neighboring Onondaga and Oswego counties.
EEE is rare, but nearly one-third of its victims die from their symptoms, which include the sudden onset of a headache, high fever, chills and vomiting. Those who survive infection may still face lasting brain damage. People of all ages are susceptible, but people over 50 and younger than 15 are at greatest risk for acquiring the virus.
There have been only 11 confirmed EEE cases in humans since 1971, the three most recent taking place in 2015.
