I wouldn't cruise, not because I of my Transplant. But because of the retroviruses common on cruise ships. I am 14 months out and I use all the precautions. Wash hand all the time. Avoid food that is not ready made etc. I do eat at buffet. I f the food looks old wait for a new batch. I have asked for fresh serving because of my Transplant and servers are more than helpful.😁
