So are you saying that the flu has similar symptoms to Covid?If someone has mild covid-like symptoms and negative covid tests, it could just be the flu. No reason it has to be a new invisible covid variant.
Where did the flu go?
You haven’t seen the flu for 2 years because transmission dropped below 1. We’ve been fighting it. Too many people wearing masks, meeting outside, staying home for small sniffles, running air cleaners, opening windows, and so on.
When enough people go back to normal, the flu will go back to normal, too.
Genuine question (since I rarely ask one), is it possible for a dominant virus to push out other viruses? For example, can a virus be more contagious so that it beats other viruses to the host?
