 Listeners, as of November 20th, 2025, public health officials in the United States are urging everyone to take this year’s flu season seriously. According to STAT News, the United States is facing another tough flu season, with a new variant of the H3N2 influenza virus, known as subclade K, making people more susceptible to infection. This variant appeared after vaccine manufacturers finalized this season’s flu shot, potentially lowering the effectiveness of the vaccine against this strain. Despite concerns about a vaccine mismatch, experts, including Scott Hensley at the University of Pennsylvania and Kanta Subbarao at Laval University, emphasize that getting a flu shot provides important protection, especially against hospitalization, and also covers other strains. This is particularly important as H3N2 viruses accounted for about half of last winter’s severe flu activity in the country, and over 63% of current lab-confirmed cases belong to the H3N2 family. While the vaccine’s effectiveness may decline as the season goes on, early studies from the UK Health Security Agency suggest children and teens receive up to 70 to 75% protection against severe flu, and adults about 30 to 40%. These numbers could drop over time, so officials are closely tracking the situation.

Listeners should also be aware of a sharp increase in pertussis, or whooping cough, outbreaks nationwide. KFF Health News and ProMED report that states like Texas, Florida, California, Oregon, and several others are facing their highest number of cases in over a decade, with Texas recording more than 3,500 cases by October and the nationwide figure for early 2025 running 25 times higher than two years ago. The surge is fueled by falling vaccination rates, waning immunity, and delays in public health tracking. Infants are at the highest risk, with complications including pneumonia, hospitalization, and, tragically, death. The CDC is strongly recommending that pregnant women get a Tdap vaccine with every pregnancy to protect babies through transferred antibodies. Obstetricians, pediatricians, and family doctors are urged to review vaccine status with all patients, and families with young children should make sure they’re up to date on all recommended shots for flu, Covid-19, and RSV as the holiday season approaches.

There have also been recent health alerts tied to infant botulism outbreaks linked to infant formula, as noted by the Minnesota Department of Health, and ongoing measles activity in states like Arizona, New York, Missouri, Utah, and Minnesota. ProMED confirms an alert about infant botulism and measles cases, stressing the need for vaccination and vigilance, especially in communities with outbreaks.

Food safety is critical going into the holidays, with the FDA expanding recalls related to salmonella found in moringa leaf powder and more cases of foodborne outbreaks. Families should pay attention to food safety notifications and follow local advisories.

In patient safety news, 3B Healthcare reports that U.S. hospitals have recorded better-than-expected improvements this year, such as lower mortality and infection rates and a surge in cancer screenings.

To sum up, health agencies stress the importance of flu shots this season, vigilance against whooping cough and measles, checking vaccine status for all family members, ensuring infant formula safety, and practicing careful food handling.
