Part of the problem is the fact that we don't fully understand this virus. We make educated guesses based upon our experience with other viruses. Bit that doesn't mean those lessons apply to this virus.

So how infectious is this via aerosolized fomites? If someone (infected) sneezes in an elevator, for how long is the air in that elevator contagious? What about the reports that this may be present in feces, and thereby contagious via the fecal-oral route? If someone poops, can the viral particles be aerosolized and inhaled by others, even a day later? We don't know, so I think it's difficult to establish appropriate safety criteria. Maybe we'll know more in a month.
