      • Viral Surveillance: The most frequently identified influenza virus type reported by public health laboratories during week 9 was influenza A, with influenza A (H1N1)pdm09 viruses predominating. The percentage of respiratory specimens testing positive for influenza in clinical laboratories increased.

      • 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: Two influenza-associated pediatric deaths were reported.

      • Influenza-associated Hospitalizations: A cumulative rate for the season of 10.4 laboratory-confirmed influenza-associated hospitalizations per 100,000 population was reported.

      • Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 3.5%, which is above the national baseline of 2.1%. All 10 regions reported ILI at or above region-specific baseline levels. Puerto Rico and 10 states experienced high ILI activity; New York City and 13 states experienced moderate ILI activity; 12 states experienced low ILI activity; 15 states experienced minimal ILI activity; and the District of Columbia had insufficient data.

      • Geographic Spread of Influenza: The geographic spread of influenza in Puerto Rico and 37 states was reported as widespread; Guam and 13 states reported regional activity; the District of Columbia reported local activity; and the U.S. Virgin Islands reported sporadic activity.
