I still don't know what happens in this scenario:
When away having tested negative before departure, u then get a positive test before the flight back home?
Are u marooned abroad in a random quarantine accommodation when positive waiting to get ill? Do u look for it yourself?
How often would u then retest?
If virus can still show up for 3 months in tests, would u still have to wait for a negative test?
Please enlighten me!
