There's a passage down the bottom of to the page of the carnival COVID link. See below. It looks like simply having a recent positive is enough but I just want to make sure the documentation I have is sufficient to NOT need a rest
DOCUMENT OF RECOVERY**
Guests who have recovered from COVID-19 within 3 months of their sailing date do not need the required pre-cruise test if they are at least 10 days past their positive test result date, have no symptoms and produce document of recovery from COVID-19. A Document of Recovery is accepted from both fully vaccinated and unvaccinated guests (with a Carnival-approved exemption) and consists of a paper or electronic copy of the positive viral test result from a certified laboratory (dated no more than 90 days prior to the sailing date).
