@eris if masks and lockdowns work why do places with lockdowns that release their lockdown often see an ease in cases? Also, if masks and lockdowns work, why do places with lockdowns fairly consistently have higher death totals than places that don't, all the while other comparisons yield have nearly no difference?
There's literally no logical reason for there to be 0 cases of flu, and no, if the masks and lockdowns were sufficient enough to stop the flu, they would have helped at least somewhat consistently with COVID, and since COVID numbers are either higher or no different than places without lockdowns versus with them, there's literally no way for that to be true.
Furthermore, there's nothing we *did* that would have eradicated the flu since COVID started, we didn't do anything except enter a pandemic and by March 2020 flu had started dropping, which was before a lot of the lockdowns. There's no causal link between masks and flu disappearing.
