As a veteran of 32+ cruises and 36 or more countries visited, I would be much more scared traveling to any 3rd world country, compared to a cruise on a modern cruise ship.
I am a numbers man due to my engineering background, and there are 300+ cruise ships prowling the oceans at any time, so in the last 2 months time there have been 300 x 8 = 2400 cruises, and only a couple of cruises are in the news with infections. Even the large Grand Princess ship has only 2 passengers got infected with the virus.
“I am a numbers man due to my engineering background...”
I guess I can’t match those standards, but feel free to head out on a cruise ship, I’m sure it will be very ‘memorable’.
You know they tested less than 1.4% of the total people onboard (45 tested of 3534 on board), right? And 21 of those tests, or 46% came back positive. From the very limited information given, the tests were done on crew members with symptoms and the 15 or so passengers who were on both the Mexico Cruise and the Hawaii Cruise. The odds that "only 2 passengers" were infected are incredibly small. The infections are most likely in the hundreds.
Your point about the vast majority of cruises actually having ZERO infections is true, at this early stage. That will change. My sister is 10 days into an 18 day cruise right now. She loves cruising and wasn't going to miss this one over the small number of ships having problems.
