It's possible, maybe even likely. Just once, on one ship, would be enough for a panic exodus of ALL ships currently at sea, wouldn't you think?
Full disclosure: I've never been on a cruise, and never intend to...
IMHO the ship returns to the port it sailed from, and the port health oficials subject the crew and passengers to testing and quaranteen, and other regulations.
If the ship returned to this country, the lawyers and hostile PRESS and TV and our CDC show up and make it sound like the plague has arrived here, and will be spread by departing passengers, who need to be quarantined also, and all cruise ships cancelled from cruising until further notice. -Tom
I did my cruising 50 years ago in the navy, I’m good. Plus all the neuro viruses they’ve had before the china flu. Surely, no thanks.
That happened here in ft. Lauderdale.
