I agree with all you say, and it is a case of isolation until ruled out.
But, given our different professions, I am in no doubt that you are seeing the more serious cases, whereas I am seeing more of the media-frenzy-induced BS cases of general malaise with associated sniffles, which would ordinarily be treated at home with chicken soup and tylenol. Some of them are not even getting swabbed.
I know we have had a couple of type A admits (versus the many, many more sent home) but as we all know, there are usually other factors or comorbidities present.
