CDC Declares Flu Epidemic in the US – How Does it Differ from Previous Years?

Every year in the United States, influenza (flu) reaches epidemic levels and this year is no different. However, the Centers for Disease Control and Prevention (CDC) recently acknowledged that the predominant flu strain this season is the H3N2 virus – a strain that is not well-matched to this year’s flu vaccine. It is still too early to tell if this year’s flu season will be more severe than years past, but states in the south, west and Midwest have all been hit hard by virus, according to reports.

This week, U.S. flu activity continued to increase in intensity and expand geographically in many areas of the country, according to CDC reports. Flu activity is expected to continue in the coming weeks, with increases occurring in states that have not yet had significant activity. CDC continues to recommend vaccination as long as flu viruses are circulating and prompt treatment with flu antiviral drugs for people at high risk of serious flu complications.  

For a summary of key flu indicators and additional information about this season’s flu virus, please visit the CDC website.
