Multiple Surveillance Systems Track an Active Flu Season

Date and Time

Monday, April 1, 2013 at 12:30 PM - 1:30 PM EDT


Scott Epperson, Epidemiology and Surveillance Branch, Influenza Division, Centers for Disease Control and Prevention


Each season in the United States a multi-component influenza surveillance system monitors and describes influenza activity. This presentation will describe the overall picture of influenza virus circulation and compare data from each of the surveillance components to previous years to better understand what turned out to be a season with high levels of activity. Also, to provide a global context for this season, data from the U.S. will be compared to other Northern Hemisphere countries, and a selection of vaccine strains for the 2013-2014 will be covered.


  • Describe the components of seasonal influenza surveillance in the United States and how they were used to monitor the 2012-2013 influenza season.
  • Update participants on influenza activity from other Northern Hemisphere countries.
  • Provide a short update on 2013-2014 influenza vaccine strain selection.
