Flu Cases Surge: Are You Protected This Season?
31 Dec
Summary
- Flu cases are rising faster than in previous years across the US.
- At least 7.5 million illnesses, 81,000 hospitalizations, 3,100 deaths recorded.
- Holiday travel, low vaccination rates, and misinformation contribute to the spike.
Flu infections are escalating nationwide, with current data from the Centers for Disease Control and Prevention indicating a faster rise than in prior years. As of December 31, 2025, preliminary estimates show at least 7.5 million illnesses, 81,000 hospitalizations, and 3,100 deaths for the ongoing season.
Public health experts attribute the surge to a confluence of factors, including extensive holiday travel, lower-than-desired vaccination rates, and the spread of health misinformation. A significant concern is the rapid spread of a particular influenza A(H3N2) variant, subclade K, which constitutes nearly 90% of characterized viruses collected since late September.
Despite a recognized mismatch between the circulating flu strains and the current vaccine, health officials strongly advise vaccination for everyone six months and older. While the virus has mutated, inducing some antibodies through vaccination can still aid in fighting the disease. Flu activity is expected to persist for several more weeks.
