NEW ROCHELLE, NY (September 1, 2023) — The first positive human case of West Nile Virus this year has been confirmed in a New Rochelle resident.

The Westchester County Department of Health evaluated standing water around the resident’s home and nearby catch basins, and treated those with larvicide as needed.

This season’s first two batches of mosquitoes carrying West Nile Virus in Westchester were found in Rye and Mamaroneck.

West Nile Virus infection most often causes a mild or moderate flu-like illness, but can be more serious particularly for people age 60 and older, and those with other health complications.

What they are saying:

Westchester County Health Commissioner Sherlita Amler, MD: “This first case of West Nile Virus should remind us all to take precautions against mosquito bites by removing standing water from our property, and using repellents when we spend time outdoors, especially from dusk to dawn when mosquitoes are most active.”

Residents should inspect their property and remove any standing water to prevent mosquitoes from breeding. Residents who notice large areas of standing water on public property should report them to the Westchester County Department of Health at (914) 813-5000.
