A new variant of influenza A, H3N2 subclade K, is spreading rapidly in the Northern Hemisphere, raising concerns about a severe 2025-2026 flu season. This variant has seven new mutations that may help it evade immunity from current flu shots. The variant was first detected in Europe after this season’s flu vaccines were selected and has already caused early and severe flu seasons in Japan and the UK. It’s now widespread in Canada and present in most US states, making up the majority of analyzed H3N2 samples.
The CDC estimates at least 4.6 million flu cases, 49,000 hospitalizations, and 1,900 deaths have been reported this season. H3N2 viruses, including subclade K, are historically linked to more severe illness, especially among older adults and young children. Despite concerns, experts emphasize flu vaccination remains critical. The current flu shot offers substantial defense against severe illness, hospitalization, and death, and covers H1N1 and influenza B strains.Symptoms of the new variant resemble typical influenza A, including fever, chills, and cough, which overlap with COVID-19 symptoms. Clinicians urge testing, including at-home “3-in-1” rapid tests.
