Synopsis: During week 19 (May 6-12, 2012), influenza activity declined nationally and in most regions, but remained elevated in some areas of the United States.
o U.S. Virologic Surveillance: Of the 2,171 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, 288 (13.3%) were positive for influenza.
o Pneumonia and Influenza (P&I) Mortality Surveillance: The proportion of deaths attributed to P&I was below the epidemic threshold.
o Influenza-Associated Pediatric Mortality: Two influenza-associated pediatric deaths were reported. One was associated with an influenza B virus and 1 was associated with an influenza A virus for which the subtype was not determined.
o Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 1.2%, which is below the national baseline of 2.4%. All regions reported ILI below region-specific baseline levels. Two states experienced low ILI activity; New York City and 47 states experienced minimal ILI activity, and the District of Columbia and 1 state had insufficient data to calculate ILI activity.
o Geographic Spread of Influenza: One state reported widespread geographic activity; 5 states reported regional influenza activity; 11 states reported local activity; the District of Columbia, Guam, Puerto Rico, and 30 states reported sporadic activity, and the U.S. Virgin Islands and 3 states reported no influenza activity.
