UMEM Educational Pearls

Background:  As discussed previously, influenza (flu) is a common respiratory disease that causes significant morbidity and mortality worldwide (see pearl from October 1. 2014).  We are now in the midst of the current flu season.

 

Current Update: This year’s vaccine was only a partial match (<50%) for the current influenza A (H3N2) circulating virus, so there is a significant potential for a “bad” flu season with widespread disease and severe illness.  Currently, influenza is now widespread throughout the US, with some states reporting more activity than others.  The CDC has a weekly surveillance map that highlights current disease spread.

 

Bottom Line:

  • Remember that influenza annually causes between 250,000 and 500,000 deaths worldwide.
  • Your emergency department will likely see many individuals with influenza this year, even if the patient received the vaccination.
  • Know your emergency department protocols and policies for cohorting influenza patients  and addressing droplet isolation precautions.
