First Positive West Nile Virus Case in Westchester in 2025

County Health Department Reminds Residents to Remove Standing Water and Use Repellents

Westchester County has learned of its first positive human case of West Nile Virus this year, which was confirmed in a Yonkers man.

Health Commissioner Dr. Sherlita Amler said: “This first case of West Nile Virus should remind all of us to remove standing water around our homes every time after it rains, and use repellents when we spend time outdoors, especially from dusk to dawn, when mosquitoes are most active.”

The Westchester County Department of Health will evaluate the nearby area for standing water around the resident’s home and nearby catch basins, and treat those with larvicide as needed.

Residents should walk around their property and remove any standing water to prevent mosquitos from breeding. Check flower pot drip trays, kiddie pools, play equipment and other items left outdoors.  Residents who notice large areas of standing water on public property should report them to the County Health Department at (914) 813-5000.

Throughout the season, the County Health Department traps and tests mosquitoes to track the presence of viruses they carry. For more ideas on how to reduce the mosquito population near your home, go to https://health.westchestergov.com/west-nile-virus
