I got a particularly bad dose of covid 3 months back which left me bedridden for 5 days and house bound for another 5. Just wondering what happens if you are on a 30 day exempt entry and you come down with covid on say, day 28. You'd have to get a PCR test as evidence I would imagine which would mean a lot of public exposure, and you'd hardly be able to front up to immigration for a visa extension.I have taken out insurance that includes sickness and trip disruption, but that's not going to help with overstay. (I turn 70 while away)
