A Highly Contagious Strain of Flu Spreads Across Europe and North America

A mysterious strain of flu that has been reported in outbreaks across Europe and the US is a new variant of the influenza A H3N2 virus, specifically subclade K. The World Health Organization (WHO) and other health experts have confirmed that this particular strain poses significant concerns due to its unusual characteristics. While existing vaccines were widely distributed during the 2020-21 flu season, they appear to be less effective against the current variant, sparking fears of widespread illness and potential shortages in medical supplies.
