Clinical Trend of the Week (February 25 – March 3): Influenza A

"Elevated" activity led to an elevation in the popularity of this week's top search term. The US Centers for Disease Control and Prevention (CDC) recently noted that influenza activity in the United States increased beginning in mid-December and remained elevated into February. Influenza A viruses comprised the majority of circulating viruses, with vaccine effectiveness against that group estimated to be 43%. Combined with the vaccine's 73% effectiveness against influenza B viruses, the results show that vaccination reduced the risk for outpatient medical visits by nearly half. As clinicians across the country continue to battle seasonal influenza, this term will no doubt remain of much interest.
