Borough Park recorded 59.13 influenza cases per 100,000 people for the week ending October 24, 2026, the highest rate among New York City neighborhoods. The citywide rate for that week was 29.30 cases per 100,000 people, after city influenza cases nearly quadrupled between September and October 24.
Why it matters
The concentration of cases in certain neighborhoods shows how influenza activity can vary widely across New York City within the same week. Residents in Borough Park, Brooklyn and other elevated areas face higher local exposure during the current flu season.
Surveillance data shows Borough Park at 59.13 influenza cases per 100,000 people, roughly double the citywide rate of 29.30 for the week ending October 24, 2026. Influenza A H1 cases reached 498 that week compared with a September weekly average of 57, and the reasons for the neighborhood variation remain unexplained.
The players

The municipal health agency that operates the city's influenza surveillance system and publishes neighborhood-level case rates.

Big Picture
The neighborhood-level rates reported by the New York City Health Department's influenza surveillance system allow comparison across boroughs within a single reporting week. This week's figures show a sharp concentration in Brooklyn and Manhattan neighborhoods compared with the citywide average of 29.30 per 100,000.
Residents in higher-rate neighborhoods such as Borough Park and the Upper East Side face greater everyday exposure to influenza during the current season. Standard precautions such as vaccination and staying home when ill apply regardless of neighborhood.
The takeaway
Neighborhood flu rates can differ sharply within the same city, so checking local surveillance updates can help residents gauge their own exposure. Vaccination and early testing remain the most direct steps during a rising season.
