I appreciate the response, but I don't know that it's correct. Wouldn't make sense, because the whole point of the COR is to excuse lingering positives from previous infection, and I'd be more concerned about lingering positives on a NAAT. I've asked Royal, so I'll see if I even get a response, but I don't see anything in the FAQ that limits the exception to pre-cruise testing.
In any case, I may have everyone test again precruise anyway, and if it's negative I won't have to worry about the COR.
