CDC resumes weekly flu activity reports

Information about influenza activity in the United States is collected, compiled and analyzed by the Centers for Disease Control and Prevention (CDC) and published in a report called FluView. CDC has resumed full FluView reporting for the 2015-2016 U.S. flu season and has made a number of refinements to the report this season.

FluView includes information on:

• when and where influenza activity is occurring in the United States,
• what influenza viruses are circulating, and
• the impact of influenza disease in the United States, including flu-related illness, hospitalizations and deaths.

FluView is available in a downloadable PDF report, but the information also is available in interactive applications (FluView Interactive), which allow users to create and customize dynamic visuals.

This season, a number of refinements have been made to FluView including:

• Differentiating data provided by public health and clinical laboratories,
• Providing lineage for influenza B virus data,
• Displaying graphically the age distribution of influenza-positive specimens,
• Transitioning to the National Center for Health Statistics electronic mortality surveillance system, which provides a more complete and accurate assessment of deaths from flu.

Subscribe to the FluView RSS feed for updates and news. The reports are posted weekly on Fridays.

Additional Information

• Influenza activity is low at this time, but there are early signs that activity is increasing.
• CDC recommends that everyone six months of age and older get vaccinated against influenza every year.
• Influenza viruses are constantly changing so the composition of the seasonal influenza vaccine is reviewed annually and updated periodically to better match circulating viruses.
• The composition of the 2015-2016 season’s influenza vaccine has been updated to better match circulating influenza viruses.
• Laboratory data indicate that most circulating influenza viruses remain similar to the influenza viruses used to make this season’s vaccines; this suggests that vaccination should protect against most circulating influenza viruses.
• As of October 30, 2015, more than 118 million doses of 2015-2016 flu vaccine have been distributed.
