The flu isn’t done yet, as new data suggests infections are rebounding

The CDC reported Friday that influenza B strains are edging up by less than a percentage point, concentrated in school-age children, ages 5.
The season, driven by an emergent H3N2 subclade, sees an uptick in B distinct from subclade K, while the winter storm that affected about half the US last week may influence trends amid child deaths reported last week.
Lab surveillance for the week ending January 24 shows 87% A strains and about 13% B strains, with eight more pediatric flu deaths last week raising the total to 52.
This year's flu vaccine protects against two A strains and one B strain, offering some protection, and both flu A and B cause similar symptoms treatable with antivirals amid rising Covid-19 and respiratory syncytial virus activity.
Whether this marks a spring wave remains uncertain, as Dr. Caitlin Rivers described it as a second peak similar to last year's late-February second peak.
