How come cruise ships are such strong vectors? Extended repeated contact?

Relatively large populations in a small confined space, the inability to truly quarantine someone who is ill, inadequate disinfection of surfaces between loads of passengers, poorly maintained waste disposal systems, sewage, etc.
Paradise for the hardy, infectious virus.

I was just thinking about this the other day. If you zoom way out on the size scale, it's basically a sealed tube of creatures producing filth and bacteria, which can't be ventilated because it's a maze like an anthill.

Everyone brings their own mix of shit they've mostly gotten over. The added viral load decreases your immune system's ability to fight any one disease. And everyone's mingling and coughing on the shrimp.
They're like a petri dish with agar made of rich folks.

Just easy to measure. Coronavirus Is probably already way more spread than we know, just in a more unreachable population.
One example: the first coronavirus death in Spain happened well before the first case was detected. They discovered it through autopsy weeks later

They are like petrie dishes, but with people. Extended repeat contact of people _and the surfaces they come in contact with_.
