Overview

  • National indicators are rising again toward a second peak, with infections climbing most in school-age children as H3N2 subclade K remains dominant and influenza B inches up.
  • CDC estimates for the season now total roughly 20 million illnesses, 270,000 hospitalizations and 11,000 deaths.
  • Fifty-two children have died so far this season, and about 90% of those with known vaccine status were unvaccinated.
  • Children recorded the highest peak weekly hospitalization rate since the 2010–2011 season, reflecting the outsized pediatric impact this year.
  • Experts report the vaccine’s match is reduced yet still protective—about 70% to 75% effectiveness in children and 30% to 40% in adults—while urging late-season vaccination, prompt antivirals for eligible patients, masking and staying home when sick, especially for higher-risk groups.
