US EditionFlu Season in the US Is Heating up, Driven by New Subclade K Variant
- This year, subclade K is driving a rapidly intensifying United States flu season, with Richard Martinello warning it will be more severe than typical and expected to dominate the holiday period.
- Because the vaccine was selected almost a year earlier, the current vaccine edition mismatches the circulating strain, while genetic changes in the virus reduce antibody recognition and increase transmissibility.
- Vaccination coverage in the U.S. remains low among children and seniors, with just 36% of U.S. children vaccinated and adults 65 and older at 13%, despite CDC analysis showing vaccines still help reduce hospitalizations by nearly 50% in the Southern Hemisphere.
- Experts say getting vaccinated is the first step to stem severity, while preventive actions like staying home and wearing a mask reduce spread, and early consultation benefits from effective antiviral drugs.
- Record Southern Hemisphere surges last year in Australia and Brazil signal broader risk, while global travel and holiday gatherings will magnify spread and vaccine hesitancy combined with vaccine mismatch could worsen outcomes.

Flu season in the US is heating up, driven by new subclade K variant
The latest data on respiratory illness in the United States shows that shoppers and merry-makers are spreading more than just holiday cheer: They’re also passing around germs. In many cases, it’s a new virus variant that’s been causing early and busy flu seasons in Asia, Australia and Europe.
