A vaccine is 1-2 years away. It's likely the majority will be infected before then. It is unclear if you can continue playing whack-a-mole with quarantine measures for the next 1-2 years. It's possible but unlikely, at least in the West. The UK's gambit is that by timing stricter quarantine measures they can cut the head off the peak, while slowing down spread due to some immunity in the population. This may work if the risk groups can indeed self-isolate for 4 months, and if more ventilators can be manufactured at speed. It will still be devastating. It will be interesting to see what happens in China after people return to work. Either way, I think we are looking at bans on international travel to continue for many months to come.
