    Synopsis: During week 1 (January 1-7, 2012), influenza activity in the United States remained relatively low.

    • U.S. Virologic Surveillance: Of the 3,199 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, 108 (3.4%) were positive for influenza.

    • 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.

    • Outpatient Illness Surveillance: The proportion of outpatient visits for influenza like illness (ILI) was 1.4%, which is below the national baseline of 2.4%. All 10 regions reported ILI below region-specific baseline levels. Two states experienced low ILI activity, New York City and 48 states experienced minimal ILI activity, and the District of Columbia had insufficient data.

    • Geographic Spread of Influenza: The geographic spread of influenza in two states was reported as regional; seven states reported local activity; 37 states reported sporadic activity; the District of Columbia, Guam, the U.S. Virgin Islands and four states reported no influenza activity, and Puerto Rico did not report.
