They might very well be immune, or they were never in the house to begin with. My Mom is immune to chicken pox, never got the vaccine and all of us had the chicken pox but she never got it. She had a blood test and it showed she is immune to it, not sure if someone can be immune to Ebola, I doubt it, which makes me think they were never in the house
There are pictures of them coming out of the apartment, they were there.
The idiot county judge was in the apartment as was the deputy sheriff that served papers for forced quarantine.
If his family doesn’t get Ebola then the main question for the CDC should be why didn’t they get it, is there a natural immunity.
