Travelling from SA to Mauritius via Dubai

Hi Alta,
I don't know how relevant this info is given that we travelled from Dubai to SA mid December 2020.
At both check in counter and gate, the staff were adamant we have our covid papers in order i.e. printed out reports that showed we had a negative Covid result from the previous 72hours. Our 7 yo son did not have a report to print out (because of his age) only a negative status and they were ready to bump us off the flight. We had to scramble to find evidence that he had taken the test as well as show the doctor's signature on the report so that they would let us on the flight.
As long as your (Covid) papers are in order (which show the negative result along with the lab's name and doctor's signature), you should be fine.
Hope this helps
Ann
