H1N1 (Swine Flu): New FluView Shows Continual Improvement Across the U.S

Although people are still getting sick and deaths are continuing, the pandemic picture is continuing to improve as the second wave continues its downward trend.  The CDC FluView report is delayed this week due to the Thanksgiving holiday.

  • Over 99% of all subtyped influenza A viruses being reported to CDC were 2009 H1N1.
  • The proportion of deaths attributed to pneumonia and influenza (P&I) was above the epidemic threshold for the eighth consecutive week.
  • Thirty-five influenza-associated pediatric deaths were reported.
    • Twenty-seven of these deaths were associated with 2009 influenza A (H1N1) virus infection, seven were associated with an influenza A virus for which the subtype was undetermined, and one was associated with a seasonal influenza A (H1) virus infection that occurred in March.
  • The proportion of outpatient visits for influenza-like illness (ILI) was 4.3% which is above the national baseline of 2.3%. All 10 regions reported ILI above region-specific baseline levels.
  • Thirty-two states reported geographically widespread influenza activity.
