CDC says coronavirus survived in Princess Cruise ship cabins for up to 17 days after passengers left

12. There are some assumptions baked into the reading.

It says it could survive. OP doesn't say how much.

We don't know how much is necessary for infection. Yes, one virus particle could, in principle, produce an infection. But, in principle, all the gas in the room I'm in could suddenly wind up randomly heading to one corner of the room. One person said, in jest, that the way you say "no" in French is "en principe ..."

Then there's the explicit warning that we haven't actually shown that it's all that easy to catch the virus from a surface.

Really, it most likely started with some bats in a cave somewhere in Hubei Province, jumped to pangolins about 6 years ago when one ate something with batshit on it, and then to humans in October or November 2019 when a human ate some part of an infected pangolin or just spent too much time incautiously handling the pangolin (the way that MERS jumped from camel to human a while back).
