It appears that there is really no rhyme or reason for people getting infected with COVID or not. It is around everywhere as a very highly infectious variant. So really no need to beat ourselves up over how we were exposed or got it. No matter how many boosters, masks, social distancing, it seems not to matter much. Be prepared to get at least a mild case on a cruise ship or immediately following your cruise. If it doesn't happen, then you missed it that time. You are either lucky or unlucky at this point. That is what we all need to think about and live with. If this is uncomfortable to hear about your cruise, then maybe choose another vacation option. As for me, if I can cruise without fear of hospitalization or worse, it is a risk I will choose to take.
