“The only action on positive results on asymptomatic people is to quarantine them. That result does not add to our knowledge relevant to making protective measure decisions.”
How so? If we can determine that there is a predictable percentage of asymptomatic people walking around we can predict the spread and infection rate with much greater certainty. We can also determine high risk individuals might need to further self isolate.
The asymptomatic would have to self isolate and stay away from high risk people. But we would not learn anything that we don't know by looking at hospital data. We can decide on reopening a lockdown based on the number of admissions. If those drop to nothing, that means people aren't getting sick.

We can determine the prevalence of CV by testing cross sections of the population like we are already doing. The cross section tests are pointing out whether there is a need for further isolation. The reports I’ve read say that positive cases are maybe upward of 10 times as prevalent as detected cases. That’s a lot, but it means that the death rate is much lower than feared.
