Covid 19 virus

I'd say the main benefit of broad testing is you get big numbers early. That scares the shit out of the all the idiots and helps confining the spread.

On the merit of testing people that are asymptomatic and didn't have contact to someone known contagious: I don't think it makes much sense. There are not enough test kits and if you test negative, you'll catch the bug later and use up another test kit. It's better if everyone behaved as if they were already infected.

From those it is clear that a lockdown will only slow the Corona virus down. As soon as the lockdown is relaxed the spread will continue. A vaccine combined with herd immunity are the only effective weapons we can use.

Why didn't that lockdown relaxation phenomena you describe happen with SARS? And MERS?

That only works for people who live alone.  Within families you would really like to know what the deal is.  We need those instant home test kits people are working on.

generalized testing is useless
the first thing SK authorities did was contact tracking and focused testing

BTW test kits are themselves abundant (Italy recently produced and shipped half million of that to the US)

the problem is the logistic of testing itself, you need lots of people to take the tests and to analyze them
besides that they are not 100% reliable... there are always some false positives or negatives and people who are negative today may be infected tomorrow

FWIW, here's an interesting video posted the other day analyzing the WHO statistics for the present status of the global COVID-19 situation. There's also a part 2 looking at the US in particular.
