It's strange to call this an "alternative explanation", since it's the one that expert infectious disease researchers, nearly without exception, are pointing to. The (let's face it, silly) notion that masks and distancing suppressed all respiratory pathogens except one is a theory with very little traction, and which will almost certainly not stand up to serious scrutiny.
Blasphemy! Anyone paying attention can see that every person with the flu was labeled as having “Covid” but everyone who “follows the science” will perform all kinds of mental gymnastics to avoid seeing what is obvious.
I got a cold a few weeks ago. Got tested, it wasn't Covid. Where mental gymnastics are needed is in ignoring hospitalization and excess mortality statistics.
