Are you sure the tests can detect the virus two days after exposure? One reason the CDC advises quarantine and waiting for symptoms before testing is because they aren't sure it can be detected before symptoms start.

Though I guess whenever you are producing enough virus to be contagious you would probably test positive at that point too.

I'm not sure; that 2 days number was what I thought I'd read about South Korea's test, but could be wrong.

At any rate, that's an approximation. The key point is for the average testing and isolation interval to be shorter than the average time to pass on a new case, whatever that interval actually is. If that happens, then it's stoppable.
