Westchester County has learned of its second human case of West Nile Virus this year, which was confirmed in a 66-year-old resident with underlying medical conditions, who is hospitalized.

Health Commissioner Sherlita Amler, MD, said, “This second case of West Nile Virus should serve as a reminder for all of us 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.” 

West Nile Virus infection most often causes a mild or moderate flu-like illness, but can be more serious, particularly for people 60 and older, and those with other health complications. Last year, three people were diagnosed with West Nile Virus, and in 2019, one Westchester County resident had the virus.

The Westchester County Department of Health has inspected the area around the resident’s home for potential mosquito breeding sites, and has evaluated nearby catch basins in the area and treated those with larvicide as needed.

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

Throughout the season, the Westchester County Health Department traps and tests mosquitoes to track the presence of mosquito-borne viruses. For more ideas on how to reduce the mosquito population near your home, visit the Westchester County Health Department site.
