View Week 19 Chart Data

During week 19, seasonal influenza A (H1), A (H3), and B viruses continue to co-circulate with novel influenza A (H1N1). Approximately 73% of all influenza viruses being reported to CDC are novel influenza A (H1N1) viruses.

The increase in the percentage of specimens testing positive for influenza by WHO and NREVSS collaborating laboratories may be due in part to changes in testing practices by healthcare providers, triaging of specimens by public health laboratories, an increase in the number of specimens collected from outbreaks, and other factors.

Synopsis:

During week 18 (May 3 – 9, 2009), influenza activity remained at approximately the same level as last week in the United States, indicating that there are higher levels of influenza-like illness than is normal for this time of year.

  • One thousand four hundred fifty-four (11.9%) 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.
  • The proportion of deaths attributed to pneumonia and influenza (P&I) was below the epidemic threshold.
  • Three influenza-associated pediatric deaths were reported.
  • The proportion of outpatient visits for influenza-like illness (ILI) was above the national baseline. Three of the ten surveillance regions reported ILI above their region-specific baselines.
  • Eight states reported geographically widespread influenza activity, 14 states reported regional activity, the District of Columbia and 15 states reported local influenza activity; and 13 states reported sporadic influenza activity.
