If it is same apartment building, I will wager it is one of the family members.
Except for CDC didn’t bring him in. He apparently showed up at the Emergency room.
I am thinking he was not on the “being monitored” list, and that is a frightening possibility.
Unlikely. As screwed up as CDC is, they'd at least have given the family members a number to call, rather than having them amble over to the nearest care center.
I would hate to be the owner of those apartments.
