> Imagine if 10+% of the population already had COVID and where immune

By some estimates we need over 80% of the population to get it in order to achieve herd immunity, so if only 10% of the population has it we're not very close at all to this being over.

The first 10% to be infected, are also likely to be the highest spreaders (people in close contact with a high amount of strangers). The effect should hopefully be higher than 10% reduction in the reproduction rate.

If 10% already have it wouldn't that mean we're only a few weeks away from it fizzling out, given the rapid rate at which it spreads?
