My sister has a friend who tested positive, had symptoms, and felt sick for a week, then all symptoms are gone, and felt well. She then took the test to make sure is negative before returning to work. The test still showed positive, she continues to test every few days, and test results continue to show positive. Now already 2 months, and still tested positive, so she is still not allowed to return to work. Luckily, her work has unlimited COVID time off.
For future cruise planning, I would like to make sure I understood what I read on this thread. You can still board the ship if tested positive (test taken at the port on embarkation day or taken 2 days before embarkation) if you can show proof that you tested positive 14 days or longer before embarkation and now you have no more symptoms?
