Not super recent, but on our September 16th Reflection( Italy) cruise there was a couple quarantined in their suite. We were in a Sky Suite. We saw them on Day 1, never saw them again. All meals were delivered. Trash was left at the door, we saw red bags of linens. On the second to last day, we saw the nurse visit and administer tests.
We flew home on September 26th, my wife came down with a "cold" the next day. I tested her and she was negative. She was negative on day 2 as well. She tested positive on day 3. I never tested positive, nor did I become sick. We both had our 5th booster on September 8th, 4 days before we flew to Rome.
I have to say, if she became sick onboard, I would not have reported it. We brought Paxlovid with us. There were NUMEROUS people coughing in the very crowded elevators. More than a few people on our roll call tested positive when we came home.
