Came home with Covid, again.

The time last year we went on a Carnival cruise and I got COVID but no one in my family did, that we know of. What were the chances it would happen again? High I guess. We were on the Explorer of the Seas Feb 16 - Feb 23. We flew back on Monday and when I sat down I felt a little tickle in my throat. 24 hours later I took a Covid test and it lit up. Sigh. I’m assuming I was exposed on the cruise but can’t be certain. Anyone else come home with this special gift?
