The New York State Department of Health has reported the highest number of flu cases ever recorded in a single week. According to State Health Commissioner Dr. James McDonald, “We are seeing the highest number of flu cases ever recorded in a single week in New York State. We are closely reviewing hospital bed capacity data to better understand hospitalization trends and to guide any necessary response related to impacts from respiratory viral infections. While influenza activity is elevated, there are simple steps New Yorkers can take to protect themselves and those around them, including getting vaccinated, staying home when sick and practicing everyday preventive measures. Flu is treatable for high-risk people with antiviral medicine, if taken within 48 hours of symptoms.”
Earlier this month, the department declared influenza prevalent across New York State. This declaration requires health care facilities and agencies to ensure that personnel who have not received this year’s flu vaccine wear masks in areas where patients or residents may be present.
For the seven days ending December 20, 2025, state data shows there were 71,123 positive flu cases—an increase of 38 percent over the previous week and the most since influenza became reportable in 2004. So far this season, there have been 189,312 positive cases reported statewide.
Hospitalizations related to influenza also increased by 63 percent from the previous week—from 2,251 up to 3,666 across New York.
Health officials noted that more laboratories are now testing for and reporting flu results due to multi-pathogen panels becoming standard for patients with respiratory symptoms. Despite these factors contributing to higher numbers overall, officials said this record indicates a greater impact than recent years.
Flu season usually peaks in January.
The department emphasized that it is still possible for individuals aged six months and older to get vaccinated against influenza. Those at greatest risk include young children, pregnant women, people with certain chronic medical conditions and adults age 65 or older.
Antiviral medications such as Tamiflu can be prescribed by health care providers if administered soon after symptom onset; these medicines can shorten illness duration and severity.
Officials reiterated that vaccination remains the best protection against serious illness or death from influenza and helps reduce work or school absences while protecting vulnerable community members.
Flu vaccines are widely available at pharmacies, clinics and physicians’ offices throughout New York State without a prescription for those ages two years and older; children six months or older may receive vaccinations at health care provider offices.
The Department advises additional preventive actions such as staying home when ill and following everyday hygiene practices alongside vaccination efforts.
