The flu season of 2025 has seen unprecedented levels of infection, with at least 24 million people affected in the U.S. Health experts, including Dr. Luis Ostrosky and Dr. Mark Rupp, emphasize the severity, stating that nearly 8% of medical visits are flu-related—the highest in 20 years. Contributing factors include low vaccination rates, which are below the CDC's 70% target, particularly among children. Additionally, early data from the Southern Hemisphere indicates that current vaccines may only offer modest protection, suggesting a possible trend for the Northern Hemisphere's flu activity this season.
It's hard to say exactly why that is. The way an individual flu season unveils and unrolls is a mystery, and everything from the specific viral strains circulating to the weather factors in.
Low vaccination rates may also be contributing to this year's sick season. As of late January, U.S. vaccine uptake was well below the CDC's target of 70% coverage.
