As a healthcare worker - I have been exposed many times over the last couple of years.Luckily, I have not had covid. I have also cruised 4 times in the last year and felt quite safe - First two cruises were b2b on Horizon - there were less people and maybe that is why we felt safe - no covid after two weeks. The third was Panorama out of LA and I had a bad cold before leaving and tested four times the few days before we left and was not covid positive - fourth was a quickie on the Conquest - again bad cold right before and I tested four times again pre cruise and was again negative. On the Panorama and the Conquest there were alot more people and I think the ships were back to almost full or full capacity.
Our experence I quess was that the ships were very clean and I did see hand sanitizer everwhere and I always had some in my bag and DH and I did use it very often.
People need to do what is comfortable for them. No matter where you go in the world you are going to find covid.
FYI there are even healthcare systems out there that are relaxing some of the mask rules - I wear a mask at work but when I am out and about now unless there are alot of people I don't wear a mask.
For those of you that have had covid - sorry that you had to experience it - anyway you look at it - it isn't a pleasant experience.
