During week 47 (November 21-27, 2004)*, influenza activity overall was low in the United States. Twenty-nine (2.1%) specimens tested by U.S. World Health Organization (WHO) and National Respiratory and Enteric Virus Surveillance System (NREVSS) collaborating laboratories were positive for influenza.
The proportion of patient visits to sentinel providers for influenza-like illness (ILI) and the proportion of deaths attributed to pneumonia and influenza were below national baseline values. One state reported regional influenza activity and two states reported local activity. Thirty-five states, the District of Columbia, and New York City reported sporadic influenza activity and 12 states reported no influenza activity.
Laboratory Surveillance*:
During week 47, WHO and NREVSS laboratories reported testing 1,383 specimens for influenza viruses, of which 29 (2.1%) were positive. Of these, 3 were influenza A (H3N2) viruses, 15 were influenza A viruses that were not subtyped, and 11 were influenza B viruses.
Since October 3, WHO and NREVSS laboratories have tested a total of 15,512 specimens for influenza viruses and 201 (1.3%) were positive. Among the 201 influenza viruses, 146 (72.6%) were influenza A viruses and 55 (27.4%) were influenza B viruses. Sixty-five (44.5%) of the 146 influenza A viruses have been subtyped and all were influenza A (H3N2) viruses. Twenty-nine states from all surveillance regions** have reported laboratory-confirmed influenza this season………………….. CONTINUES…………………
