Just out of curiosity, I checked the Covid positive rules for the cruise my friend went on. The cruise site does state that passengers testing positive must isolate in their stateroom or depending upon the local rules, to disembark and isolate locally. I also found a video of a guy who had to isolate for 5 days onboard a ship from the same company. So I am going to assume that rules are being followed very loosely onboard some of their ships.
Here's a video of a passenger who got Covid+ during his Vikings cruise. He was asked to isolate for 5 days but would not be required to test at the end of the 5 days. He did mention that the cruise ship did not want to tell him how many people came down with Covid on the ship and he suspected that some people who self tested and did not want to be isolated probably chose not to go to the med center to be evaluated. https://www.youtube.com/watch?v=y8G3TZiLgrQ
Here's another video, of a person interviewing her grandfather who became Covid+ on his Royal Carrib cruise. Apparently, he was coughing a lot as he was enjoying his cruise and felt that it was starting to annoy his cruise mates, so he went down to the med center to test. The med center on this ship told him that there was a "mob" of people the other day with Covid+ and that he was number 17 for the day. So quite a few people Covid+ and again, I am sure there were those who never came down to get tested because they did not want to have to isolate. Towards the end of the video, the grandfather mentions that as they disembarked, approx. 100 passengers who were all Covid+ waited to be transported to their quarantine hotel. https://www.youtube.com/watch?v=zpd9Ktn-SmA
I think I would keep my mask on onboard indoors and in crowded places just in case if I was on a cruise. Unless I just recently got boosted or recently recovered and no new variant. I remember the case I think it was in Korea at a Starbucks where there was a Covid cluster way back when, and the workers who were all masked did not get Covid even though several patrons who were not masked got it. So masking with the right masks (at least a surgical mask) works.
In Japan, because we use public transportation like trains and buses, it is expected for sick people to wear a mask when out in public, work or school. If you are caught coughing without a mask, people look at you. Also, many wear mask during allergy season. So it is not unusual to see people in around town with mask and this is before Covid. I think if everyone took personal responsibility and wore a mask when they don't feel well, and for that to become routine, then we can get through Covid becoming endemic.
