If positive, I believe that I would have had to quarantine at the resort for 5 days and then retest. I just checked and It looks like they have since dropped the post arrival test on Fiji.This is really strange. What would have happened if you had tested positive? Had to fly back home I suppose.
A friend of mine told me recently "I have done a lot of travelling recently all over. Including Namibia and Botswana. COVID is a non-issue for travel now." I've also been to Luxembourg, Turkey and the Azores over the summer - the biggest imposition was that you still have to wear facemasks on the interisland flights in the Azores. Maybe the more expensive your destination, the more of an issue it is likely still to be making of Covid. Which is a reason to avoid expensive destinations.
For many of these places, the main issue has been that they do not have the facilities/staff to handle a large spike in hospitalizations so they were just trying to keep things under control to avoid overwhelming their systems.
Unless we see spikes as we head into the fall, I suspect that many of these post arrival tests will be dropped in most places over the next 3-6 months.
