Depends what the experts deem acceptable. If you’re screened going through customs and you’ve had the virus I can see travel and work being pretty much back to normal for those folk.
I think in a couple of months we will see tests everywhere, mass produced for pennies and they’ll be used to control the flow of people around cities etc. Checkpoints at airports, hotels, bus stations, train stations and so on.
You're more hopeful than me mate.
