Re: Fluview 2012-13 Season: Weeks 41-19 (One Pediatric Death; Total 139)

During week 19 (May 5-11, 2013), influenza activity remained low in the United States.

Viral Surveillance: Of 2,416 specimens tested and reported by collaborating laboratories, 124 (5.1%) were positive for influenza.
Pneumonia and Influenza Mortality: The proportion of deaths attributed to pneumonia and influenza (P&I) was below the epidemic threshold.
Influenza-Associated Pediatric Deaths: One pediatric death was reported (influenza A); total 139..
Influenza-Associated Hospitalizations: A cumulative rate for the season of 44.3 laboratory-confirmed influenza-associated hospitalizations per 100,000 population was reported. Of reported hospitalizations, about 50% were among adults 65 years and older.
Outpatient Illness Surveillance: The proportion of outpatient visits for influenza-like illness (ILI) was 0.9%. This is below the national baseline of 2.2%. All 10 regions reported ILI below region-specific baseline levels. One state experienced low activity, 49 states and New York City experienced minimal activity, and the District of Columbia had insufficient data.
Geographic Spread of Influenza: 1 state reported regional influenza activity; Puerto Rico and 2 states reported local influenza activity; Guam and 35 states reported sporadic influenza activity; 12 states reported no influenza activity, and the District of Columbia and the U.S. Virgin Islands did not report.

No hospitalizations or deaths have occurred. At this time no ongoing human-to-human transmission has been identified and all 14 cases have reported close contact with swine in the week prior to illness onset. Public health and agriculture officials are investigating the extent of disease among humans and swine, and additional cases may be identified as the investigation continues.

Because of reporting schedules, state totals posted by CDC may not always be consistent with those reported by state health departments. If there is a discrepancy between state and CDC case counts, data from the state health department should be used as the most accurate number.
