There are tests that come back in 90 minutes now. If the testing infrastructure is not up to par, and it certainly isn't, then people don't fly. Very simple. This isn't a game. I'd hope that we'd have sorted our testing out by now but that looks like it won't be sorted out this year at all and possibly never. If countries don't want coronas coming to them, they should just ban flights from the US. Otherwise, they should accept that they will be infected. Once again, very simple.
