Well, so much for the you have to come into contact with a symptomatic person’s bodily fluids to catch this crap.

He almost certainly got less exposure than the apartment residents. If they don't have it, then he probably doesn't have it either.

I hope you are right that this guy does not have Ebola.

Don’t kid yourself. He could very well be sick with ebola while the apartment residents are not.

There are many diseases and examples where some, but not all or maybe only a few of those in contact with infected patients become ill while others show no effects just as some of those infected may survive while many of the infected do not.
