Aside from other factors like better treatments, it seems logical that mutations of the virus that make it less severe and therefore less detectable would spread more easily. Social distancing could inadvertently be breeding the virus towards banality

That might happen eventually but so far there is no evidence that any of the newer strains are less lethal than the original one. They seem to be clinically equivalent. Coronaviruses mutate slowly.
