Last Friday’s CDC FluView continues to demonstrate very little flu in the United States with the exception of the South. In fact, Week 13 actually reported 11 states with NO flu activity at all.

The South in the only region reported an active flu outbreak on Week 13.

Here is the summary of Week 13:

  • 105 (3.7%) specimens tested by U.S. World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) collaborating laboratories and reported to CDC/Influenza Division were positive for influenza.
  • All subtyped influenza A viruses reported to CDC were 2009 influenza A (H1N1) viruses.
  • The proportion of deaths attributed to pneumonia and influenza (P&I) was below the epidemic threshold.
  • One pediatric death associated with laboratory confirmed influenza A was reported; the subtype was undetermined.
The proportion of outpatient visits for influenza-like illness (ILI) was 1.1%, which is below the national baseline of 2.3%. All 10 regions reported ILI below region-specific baseline levels. Notice how far that line has dropped!
  • No states reported widespread influenza activity.
    • Three states reported regional influenza activity.
    • Puerto Rico and three states reported local influenza activity.
    • The District of Columbia, Guam and 33 states reported sporadic influenza activity.
    • Eleven states reported no influenza activity.
    • U.S. Virgin Islands did not report.
