West Nile Cases Spread Across NY Metro Area As NYC Count Holds at 5
New York
Published · Updated
Summary
- The NYC Health Department confirmed the city's first human case of West Nile virus for 2026 on August 19.
- Since then, the case count has grown to five total human cases, according to official Health Department data: three cases of the more severe neuroinvasive disease (one each in Brooklyn, Manhattan, and Queens) and two cases of West Nile fever (one in Queens, one on Staten Island). No human cases have been reported in the Bronx.
- West Nile virus has been detected in mosquitoes across all five boroughs since June, with peak activity typically occurring in August and September.
- The Health Department has identified 1,456 West Nile virus-positive mosquito pools citywide this year, prompting multiple targeted mosquito control operations since July.
- Most people infected with West Nile virus experience no symptoms. However, about 1 in 150 people can develop a serious neurological illness requiring hospitalization, with those 65 and older three times more likely to develop severe illness than younger adults.
- Here's how you can stay safe:
- Use an EPA-registered insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus (not for children under 3).
- Wear long-sleeved shirts, long pants, socks, and shoes when spending time outdoors in areas with mosquito activity.
- Limit outdoor activities during dawn and dusk, when mosquitoes are most active.
- Install and repair window and door screens to keep mosquitoes out.
- Empty standing water at least once a week from buckets, flowerpots, birdbaths, and other containers. - Report chronic standing water to 311.
- Maintain swimming pools, hot tubs, and ornamental ponds by keeping them clean, chlorinated, covered, or drained when not in use.

Timeline
The New York State Department of Health had already confirmed cases in Nassau, Suffolk, and Onondaga counties this year, reflecting a broader surge across the greater New York metropolitan area.
Westchester County confirmed its first human West Nile case of 2026 in a Yonkers resident, according to a local news source.
An additional update from the NYC Department of Health confirms, 1,456 mosquito pools citywide have tested positive for the virus this year.
Of the five total cases, three developed the more severe neuroinvasive form of the disease, which can cause encephalitis, meningitis, or acute flaccid paralysis.
According to PIX11, citing recent New York City Department of Health data, human West Nile virus cases have now been reported in four boroughs — one in Brooklyn, one in Manhattan, two in Queens, and one on Staten Island.
NYC Health Department data shows West Nile virus-positive mosquitoes have now been detected in 89 ZIP codes — more than half of those across the five boroughs. Residents can check their own ZIP code using a searchable tool on the health department's website.
The NYC Health Department announced its next round of mosquito spraying to curb West Nile virus risk, targeting parts of the Bronx and Queens on August 24th and August 26th.
Residents can reduce their risk by using EPA-registered repellent, wearing long sleeves outdoors, limiting activity during dawn and dusk, and eliminating standing water around their homes. Standing water spotted across the five boroughs can be reported to 311.
West Nile virus spreads only through mosquito bites and cannot be transmitted person to person. Nationally, the CDC has recorded 222 human cases this year, primarily in Arizona, Texas, and California.
NYC's annual average of severe, neuroinvasive West Nile cases has nearly doubled in recent years — rising from 16 cases per year between 2012 and 2021 to 31 cases per year between 2022 and 2025.
Suffolk County also reported its first human case of the year the same day, involving a Brookhaven resident over 50 who was not hospitalized.
As of this week, 1,284 mosquito pools have tested positive for West Nile virus citywide, including 504 in Queens, 354 on Staten Island, 252 in Brooklyn, 123 in the Bronx, and 51 in Manhattan.
The infected Manhattan resident's exact source of exposure — whether within the city or elsewhere — has not been determined.
