I don't have time to try and hunt down data from recent years, but I can tell you from recent conversations that this year's infection estimate is about
140x higher than the confirmed influenza samples. There's 280M confirmed, which turns into a CDC estimate of 39MM.
Out of only 1.3MM tested. So from all the cases that were suspected to be flu, and then tested for it, almost 80% were NOT the flu.
