More mosquitoes are carrying West Nile virus in New York City this year, with all five boroughs reporting detection of the virus, according to new data.

The New York City Health Department announced this month that West Nile virus has been detected in nearly twice as many mosquito pools as this time last year. The data was collected through the department’s mosquito surveillance program, which monitors populations throughout the five boroughs from spring through fall and tests mosquitoes for West Nile virus.

According to the agency’s Positive Mosquitoes data, Staten Island is the only borough to report West Nile virus-positive mosquitoes in every ZIP code.

We recently analyzed the city’s collection data as of Aug. 7, 2026, to find every ZIP code in New York City, broken down by borough, with mosquitoes testing positive for West Nile virus.
