Using
@Spekkio 's reported 1:50 assumption of confirmed to real cases (which to me seems high, I'd guess it's more like 1:20), today's numbers would indicate that 50 million people have
had COVID 19. Very different than assuming 1 in 6 Americans
currently have it. Some proportion of them undoubtedly have recovered, and we could be well on our way to herd immunity. The implication would be that future waves will be much less pronounced.
It would be nice to see some front line, mainstream effort to collect and report on that data. No testing required, just add in a reasonably safe assumption that every case >5 weeks old where the patient survived is "recovered". We could at least get some working numbers that way. Since the desired end state would appear to be either a.) herd immunity or b.) a vaccine, we could really measure our progress toward the former, while the latter is being developed.
