I wonder if that's what's happening in China?
I do wonder if that is why they had been in lockdown for so long? To make sure they actually eliminate and stamp out the virus, rather than just flatten the curve. Just doesn't seem to be much information about this side of things. IMO we need to stick with elimination and making sure we don't come out of lockdown too soon. The WHO has also just warned countries about not coming out of lockdown too soon.
