  • U.S. Virologic Surveillance: Of the 3,607 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, 756 (21.0%) were positive for influenza.
  
  • Novel Influenza A Virus: One human infection with a novel influenza A virus was identified.
  
  • Pneumonia and Influenza (P&I) Mortality Surveillance: The proportion of deaths
  
  • attributed to P&I was below the epidemic threshold.
  
  • Influenza-associated Pediatric Mortality: No influenza-associated pediatric deaths were reported.

Region 10 reported ILI above its region-specific baseline level. One state experienced moderate ILI activity, 1 state experienced low ILI activity; New York City and 48 states experienced minimal ILI activity, and the District of Columbia had insufficient data to calculate ILI activity.
