Maybe in textbooks but not in practice. Unfortunately, I have had to take a relative to the emergency room several times since SARS hit the scene and there was NO ONE in "proper protective gear" anywhere to be seen.
Intake clerks, various medical personnel AND the "Triage Nurse"..., all without even a simple mask!
Obviously, since only one suspected local SARS case has even been noted in the area (Central Florida), the precautions seem to be considered unnecessary.
I suspect that very few emergency rooms around the USA are observing the protocols you describe and will only do so AFTER experiencing a major SARS outbreak!
I am certain that it has been determined not to be "cost effective" to do so (for now)!
That's fine for exposure within hospitals but doesn't address exposure in the general populace. If it's airborne it will spread despite efforts in the hospital. Is that incorrect?
