Early 2026‑27 Flu Season Surges
Tap title to read story
The 2026‑2027 flu season is starting early, fueled by an H1N1 strain with a new mutation.
Flu activity is still low nationally, but cases are rising quickly in many parts of the country, especially the West, and two states, Louisiana and Hawaii, are already reporting moderate levels.
As of Oct.
21, flu infections are growing or likely growing in 44 states, according to the latest estimates from the U.S.
Centers for Disease Control and Prevention.
The CDC said early‑season influenza activity is currently higher than typically observed at this time of year.
Influenza A H1N1 is fueling the vast majority of cases in the U.S. so far this season, per CDC data.
That’s a shift from last winter, when H3N2 subclade K — the “superflu” — was the dominant strain.
