Cruise lines faced an existential threat when COVID first hit them hard and then shut them down. They started up again under strict CDC guidelines - all of which have been dropped one by one until all that is left is “recommendations”.
I have recently completed a six month trip aboard a cruise ship. While the ship can carry 700 passengers, for all but the last month of the trip, there were 250-300 passengers. The trip started with strict COVID defenses - mandatory vaccinations (almost all were also boosted), mandatory social distancing and masking frequent testing and so on. By the end of the cruise, these restraints were lifted and the cruise director told me that they wouldn’t have had as many COVID cases if they had done less testing. I am also in email contact with a number of people currently on ocean and river cruises.
So, in effect, I was able to observe a COVID “laboratory” aboard a ship. By the end of the cruise, over 75% of the passengers and crew had tested positive for COVID. So, here’s the deal (pretty much confirmed by JohnEBgood’s recent experience):
Regardless of the length of cruise, under current ground rules (basically no rules after August 1st), unless you have had a COVID infection over the past few months, you have a near certainty of becoming infected aboard (and because testing is no longer done, bringing it home if you caught it close to disembarkation).
You know the drill.
The more vaccinations/boosters (and the closer to the time you take the trip), the more likely you will get an infection with fewer symptoms
The mRNA vaccines (Pfizer or Moderna) are more likely to leave you with less symptoms than the others
Co-morbidities (diabetes, renal issues, lung issues, immunosuppressed, older ages etc.) mean a higher likelihood of increased symptoms
Masking and social distancing reduces the likely virus load (and, if lucky, even catching the plague)
If infected, you join the lottery of which symptoms you get, whether you need hospitalization or end up with long-COVID. The above information can help you with better odds when you play the game, but taking a cruise today will likely (almost certainly) enter you into the contest.
