The Centers for Disease Control and Prevention has combined its Influenza Division and its Coronavirus and Other Respiratory Diseases Division into a single unit, the Influenza and Respiratory Viruses Division. A notice published in the Federal Register on Sept. 9 says the Secretary of Health and Human Services approved the change on Aug. 18 and that it took effect Sept. 4.
The timing matters because the new division takes over federal work that shapes each respiratory season just as this one approaches. It tracks which viruses are spreading, characterizes new strains, supports state and local health departments, and informs vaccine and treatment decisions. For families, those functions sit behind the weekly flu and COVID data, the strain choices in each year's flu shot, and the alerts that tell clinicians what to watch for.
