Bob:
It is all about probabilities, right?
So, yeah, high ceiling is better than low ceiling, etc.
One thing I have learned in reading about this stuff is that medical professionals always assume the worst in dealing with a communicable disease, and the burden of proof is on the person who wants to claim the risk is less in some way.
Since this is a relatively new disease we should assume the worst and act accordingly, until strong evidence is there that the risk is not as great as we thought it was.
So, my motto would be test first and ask questions later.

I’m sure you’d agree that they threw that rule out the door, once China demanded they do so.
