Description
Summary:This report summarizes U.S. influenza activity since the beginning of the 2010-11 influenza season (October 3, 2010) and updates the previous report. From October through early December 2010, influenza activity remained low in most regions of the United States. Activity increased beginning in mid-December 2010 and continued to increase during January and early February 2011. Influenza B, 2009 influenza A (H1N1), and influenza A (H3N2) viruses all have been identified thus far this influenza season, and most viruses in circulation are antigenically similar to strains included in the 2010-11 vaccine.
