As the 2025-2026 flu season progresses, hospitals in New York are responding to a surge in cases by reinstating mask requirements for visitors. The move comes as the state experiences a higher number of reported flu cases than during the peak of the previous two seasons.
Rising Cases Prompt Precautions
Institutions like Glens Falls Hospital and Saratoga Hospital have announced the return of masking policies, communicating the change via social media to help prevent the spread of respiratory viruses. The New York City Department of Health and Mental Hygiene reports that current case numbers exceed those seen in recent years.
A particularly severe strain of Influenza A, known as H3 and dubbed the “super flu,” is responsible for the majority of infections. The New York State Department of Health reports that 95% of cases within the state are Influenza A/H3, with the remaining 5% being Influenza A/H1.
