Judging from how many people have caught Ebola from the man in Texas who died... So far none besides the two nurses who were in close proximity with him as he was dying, it seems that catching ebola is not as easy as catching the cold.
I get the concern about self-imposed quarantine being unreliable. The doctor in New York wandering around pretty much ruined it for this nurse.
However, the conditions (considering the relative difficulty in catching ebola) in which she was kept is probably part of what caused the issue. An isolation tent wasn't necessary.
Keeping her in a decent hotel room with access to indoor plumbing would have been better and those conditions would have given New Jersey a lot more sway over my opinion than a tent with a portable potty.
If people who were exposed to the doctor before he started having a fever get ill with Ebola, then I'll revise my position.
However, knowing what I know now - New Jersey fucked it up with the tent.
From what is known currently about Ebola, you don't have to put a person in an isolation tent to safely quarantine them.
A hotel room or comfortable hospital room which would be sprayed down with disinfectant after the incubation period would have sufficed.
