  • Description:
    During the 2010--11 influenza season, influenza activity first began to increase in the southeastern United States in November and peaked nationally in early February. Compared with the previous influenza season (2009—10, including the pandemic), a higher rate of hospitalization was observed for persons aged ≥65 years during the 2010--11 season; however lower hospitalization rates were observed in younger populations than during the pandemic year. Overall, the percentages of outpatient visits for influenza-like illness (ILI) were lower during the 2010--11 season than the 2009--10 pandemic influenza season. In the United States, influenza A (H3N2) was the predominant virus; however, 2009 influenza A (H1N1) and influenza B viruses also circulated widely, and the predominant virus varied by U.S. Department of Health and Human Service (HHS) region and by week.
