"Researchers analysed blood samples from volunteers in Southern China, looking at antibody levels against nine different influenza strains that circulated from 1968 to 2009.
They found that while children get flu on average every other year, flu infections become less frequent as people progress through childhood and early adulthood. From the age of 30 onwards, flu infections tend to occur at a steady rate of about two per decade."

Almost everyone gets influenza a every few years. It's just that many cases are asymptomatic or minor.

Nearly half of adult influenza a infections are asymptomatic and go unreported and untested.
