Forget Covid - this on the way:
This is what Google AI says about the latest flu - so it might be worth getting a vax if it covers that strain this year:
The new, rapidly spreading variant of the flu taking lives in the United States during the 2025-2026 season
is a strain of influenza A (H3N2) known as
subclade K.
While some media reports have dubbed this variant a "super flu" due to its ability to spread quickly, it is not a completely new virus, but rather a mutated version of the seasonal H3N2 virus that is better at evading immunity from vaccinations and prior infections.
Key Facts About the 2026 "Subclade K" Flu Surge:
Dominant Strain: Subclade K accounts for approximately 90% of circulating influenza A cases in the U.S. this season.
Severity: The CDC has classified the 2025-2026 season as "moderately severe," with hospitalizations and deaths surging early in the season.
Impact on Children: The strain is hitting children particularly hard, with high rates of pediatric hospitalizations and deaths reported early in 2026.
Vaccine Mismatch: Subclade K emerged after the 2025-2026 vaccine strains were finalized, resulting in a slight mismatch that reduces the vaccine's effectiveness against infection, although it still provides protection against severe disease and death.
Symptoms: In addition to typical influenza symptoms (fever, aches, fatigue), this variant has been associated with higher fevers (104-105°F) and more gastrointestinal issues like vomiting and diarrhea.
As of mid-January 2026, the CDC estimated over 18 million illnesses and thousands of deaths, with activity remaining high in most states.
