Or, the covid test is so imprecise is is counting flu as covid.

The flu count is from people who got a false negative on the COVID test but got a proper flu test and tested positive for the flu.

So the covid test could actually be picking up flu, coronavirusus, and other viruses. There may not even be a "new coronavirus." Or maybe there is and the tests are just so bad they are picking up all sorts of viruses and false positives and calling them all covid.
