U.S. Flu Season Already Off to Early Start
Significant increases in flu activity in the United States have occurred in the last two weeks, indicating that an early flu season is upon us. These increases in activity overlap with National Influenza Vaccination Week (NIVW) which was observed December 2-8, 2012.
According to CDC’s weekly surveillance report published on November 30, 2012, 48 states and Puerto Rico have already reported cases of laboratory-confirmed influenza and, nationally, the percentage of specimens testing positive for influenza is rising fast. Influenza-like-illness (ILI) activity levels in parts of the country are already higher than all of last season. Nationally, the United States reached the baseline level for ILI the week ending November 24, 2012 and 5 states are already reporting the highest level of activity possible.
