The problem is people are seeking medical care with flu-like symptoms, but are being told they don't have the flu and it's uncertain what they have. THOSE people are being sent home if they don't meet either of the (paltry) 2 parameters:
1 - have traveled abroad recently
2 - have been explosed to someone diagnosed with Coronavirus
.
#1 is fine, whatever, but there are plenty of domestic cases you could have been exposed to
#2 is the problem - with almost no one having been tested, none of us has knowingly been exposed to someone that's been diagnosed.
