Yeah, but as soon as they were aware of a single case on board, everyone single person on the ship was informed, told to stay in their room, and became paranoid about further transmission. I don't know if we'll have similar levels of obedience in the rest of the world.

There were reports that the actual procedures on the ship were extremely poor, and the quarantine was half-baked at best.

This isn't an accurate representation of how the number got to 700. The numbers were low when the ship docked. I recall in the single digits. Everyone was put on cabin quarantine, though people could leave their rooms for a window of time each day. It was quarantine and they were testing symptomatic people. I was watching mostly HK and Taiwanese news sources on it multiple times every day.

That makes me very skeptical of the WHO claim that asymptomatic spread isn't a problem.

They all got served food by the ship's crew, who still shared bunk beds and weren't really quarantined.

This is true. Do you think under those conditions, the ship would have symptomatic employees serving food or sharing bunks with asymptomatic employees? That really goes against the idea of quarantine, so I'd like to see evidence of that instead of assuming it.

I've heard it said that you have an almost 50% of catching something if you go on a cruise.

(AnimalMuppet surreptitiously crosses "take a cruise" off of his bucket list...)

Instead, just append it to the end of the list.

Cruises are pretty bad in terms of carbon footprint. We should all avoid them for more than one reason.
