As the flu season begins its seasonal transition, recent surveillance data from the US CDC indicates an early rise in influenza activity in several regions. Public health officials are emphasizing the importance of timely vaccination and preparedness, particularly in areas showing increased outpatient visits for influenza-like illness (ILI). These early signals suggest that while flu case numbers remain below historical peaks, the virus is already gaining traction, warranting close monitoring.

Key trends identified in the latest surveillance report include:

  • Elevated ILI activity in the Midwest and Southeast.
  • Diverse circulating flu strains, with H3N2 showing increased prevalence.
  • Hospitalization rates remaining low but expected to rise as transmission intensifies.
Region ILI Activity Level Predominant Strain
Midwest Moderate H3N2
Southeast Moderate H1N1
Northeast Low B/Victoria
