Rising Flu Cases and the Threat of a Severe Season

The flu season in the U.S. is rapidly worsening due to a new variant called subclade K of H3N2, with high case numbers and hospitalizations reported, especially in states like New York. While it's too early to determine the season's severity, vaccination remains crucial, as current vaccines offer partial protection against this variant. Experts emphasize the importance of vaccination, especially for vulnerable groups, despite the new strain's mutations.
