as for the collapsing people, there were a few. you prob aren't aware that the initial virus was much stronger than the variant we received in our first wave. illness and deaths were much higher here than in later variant waves.
this is the natural course for such viruses when they meet a new host. with each infection each individual virus that replicates internalises some of the host RNA and this enables the evolution of the virus to be more able to thrive and multiply at increasing rates.
so yeh. the crap you were sucked in by dear zippety doo dah has retarded your education on viruses.
and as for the flu, people began wearing face masks and socially distancing. so of course influenza didn't have a chance to spread.
