In fact Norwalk is what has shown up and that can be handled the same way, by keeping things clean.

Actually they are having an unadvertised problem with noroviruses in the shelters.

I would guess the "shelters" would be more of a disease danger than the people living in perfectly ok houses, on dry land, and drinking bottled water. At least they don't have to share showers and sleep a foot away from someone who might actually be ill with something contageous.
