Elcan, are you advocating that this testing be done until a vaccine is available? In a year? That means 120 trillion tests in the US alone; yes, with a T. Or are you just referring to the generally accepted 14-day incubation period? Because that is a mere 4.6 billion tests, with a B. And that testing cycle provides no guarantee that CoVid-19 will stay gone.
I think we can find other more scientifically and statistically directed ways to spend those resources. I must say that your method would definitely identify all cases though.
