  Synopsis: During week 51 (December 20-26, 2015), influenza activity increased slightly in the United States.
  
  • Viral Surveillance: The most frequently identified influenza virus type reported by public health laboratories during week 51 was influenza A, with influenza A (H1N1)pdm09 viruses predominating. The percentage of respiratory specimens testing positive for influenza in clinical laboratories was low.
  
  • Pneumonia and Influenza Mortality: The proportion of deaths attributed to pneumonia and influenza (P&I) was below their system-specific epidemic threshold in both the NCHS Mortality Surveillance System and the 122 Cities Mortality Reporting System.
  
  • Influenza-associated Pediatric Deaths: No influenza-associated pediatric deaths were reported.
  
  • Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 2.6%, which is above the national baseline of 2.1%. Six of 10 regions reported ILI at or above region-specific baseline levels. Puerto Rico and two states experienced high ILI activity; three states experienced moderate ILI activity; New York City and nine states experienced low ILI activity; 36 states experienced minimal ILI activity; and the District of Columbia had insufficient data.
  
  • Geographic Spread of Influenza: The geographic spread of influenza in Guam and one state was reported as widespread; five states reported regional activity; 12 states reported local activity; 29 states reported sporadic activity; the District of Columbia and three states reported no influenza activity; and Puerto Rico and the U.S. Virgin Islands did not report.
