I don't think so. It's not like somewhere like China got to lower numbers now because most of them got it and are immune. As percentage of population the number that got it is quite small. They got control of the situation because the people who had it didn't spread and they recovered. Now they are vulnerable to it being reintroduced. But they don't need full lockdown. So another scenario is that active cases subside and we don't travel or amass in large groups for a while. This is short of your two year quarantine (which by the way you didn't spell correctly, a hint for how to spell it is that it derives from Italian 'quaranta', meaning 40, for a 40 day isolation).
