This is a record flu season, one of the worst we have seen in more than a decade. After an initial peak around the turn of the new year, outpatient influenza-like illness (ILI) activity dropped for a couple weeks—before making an unexpected rebound, rising to 7.8%. This means that around 1 in every 13 visits to the doctor is for fever and either cough or sore throat. This is the highest level since 2002, though the 2009-2010 and 2003-2004 seasons come close.
