If this guy went to the hospital 2 DAYS before and was turned away then that was two days where he was symptomatic and wandering around.
The ambulance that took him to the hospital is infected. The people running the ambulance. The people at his home who changed his bedding. The car he drove in to the hospital.
I am betting there are at least a half dozen cases that are going to pop up.
And if any of those are not listening to the news and get symptoms before they go to the hospital...
Initially, did this person go to the pharmacy by himself to pick up his antibiotics? Did he sit in a common area, waiting for his prescription? And so on and so forth.. Dallas must really be on edge!
