The 2025–26 influenza season in the United States continues to be marked by elevated activity, with millions of illnesses and rising hospitalisations reported across the country. Nationwide data suggests flu-related medical visits and emergency treatments remain at historically high levels, driven by a mutated strain of influenza A(H3N2) circulating widely. Health officials emphasise that symptoms such as fever, cough, fatigue and body aches are common this season and that vaccination offers important protection against severe outcomes.
In New York City, health authorities recently noted early signs of decline in reported flu cases, but stressed that activity remains very high compared with recent seasons. More than 128,000 residents have tested positive this season, and officials warned that typical flu season patterns — with peaks extending into spring — mean vigilance is still needed.
Meanwhile, parts of the Midwest, including Michigan, are experiencing a pronounced surge in flu cases. State health leaders report significant increases in flu-related hospitalisations, with young children among those requiring intensive care and, in some instances, ventilator support. Pediatric units are seeing rising admissions as hospitals manage a broader rise in respiratory illnesses this winter.
Public health experts urge continued emphasis on preventive measures, including influenza vaccination for those eligible, good hygiene practices, and staying home when ill. They note that, while some regions may see localised downturns in flu activity, overall infection levels remain elevated and can put stress on healthcare systems throughout the remainder of the season.
