I believe they were in the apartment, but coming from a 3d world hellhole, probably had sense enough to take some precautions, and they likely have some immunity from that hellhole.
That said, since they’ve been spirited away to a place out of sight and mind by that idiot judge, I think if they became ill, the public would only find out if one of the family blabbed it on the phone or in an e-mail...
I had read that Duncan slept in every one of their beds..how the hell does someone with Ebola sleep in someone’s bed, puke like crazy in their toilet and NOT get sick..meanwhile Nina Pham wears all the proper gear and gets sick..either this family has some crazy Ebola free immune system or something fishy is going on here
