There have been no reports of human cases in Cayuga County due to mosquito-borne illnesses this year. There are currently 10 reported human cases of West Nile virus (WNV) in New York state, according to the New York State Department of Health.

"We want people to get outside this Labor Day weekend and enjoy the beauty that is New York State, but we want them to do so safely with their health in mind by taking proper steps to protect against mosquitoes that carry diseases such as West Nile virus,” Gov. Kathy Hochul said. "Prevention remains the most effective method of protection from exposure to mosquito-transmitted diseases and can be as simple as protecting your exposed skin with clothing and applying mosquito repellent.”

EEEV and WNV are primarily transmitted by mosquitos and can infect people, horses, and other animals. People at the greatest risk are those over 50 years of age and younger than 15 years of age. There is no cure or vaccine against EEE. Symptoms often appear cold- or flu-like in people. 

“Although mosquito bites are often viewed as one of life’s little annoyances, this year we are seeing more positive mosquitoes than usual. Wearing insect repellant, removing standing water and wearing appropriate clothing does reduce risk. Mosquitoes will be present in our communities until at least the end of September, so it's important to be mindful of how we can protect ourselves when spending time outdoors," New York State Health Commissioner Dr. James McDonald said.

Experts say that even if you’re in an area that’s been sprayed for mosquitoes, it’s still a good idea to wear layers or use repellent. Sprays with deet or eucalyptus and lemon oil tend to work best.

It's also recommended that people avoid standing water and stay indoors during times when mosquitos are most active, like dawn and dusk.
