Covid-19 Test for recovery traveler.

[Margaret]

My son had Covid recently, according to CDC cruise line test requirement, anybody who had a covid not less than ten days and within 90 days, do NOT need to be tested again before onboard cruise. Because within 90 days from recovery from covid, their test result will be positive.  Instead, they can show the previous positive test and also a note from healthy care provider. But I called Norwegian help desk, the person (who is a supervisor) says their police is if you test positive, you can't onboard. That is it.  I searched their website, only says if you are a recovery, you still need to be vaccinated. Unfortunately, my son is fully vaccinated including 1 booster shot, but still got the disease. Can anyone give us some advice? Like who to contact?
