One nurse breaking protocol means that our entire healthcare system is unprepared, seriously? Is there no room in your logic for the inherent fallibility of human individuals - without extrapolating this to some form of systemic failure?
Ummm, huh? A nurse in Spain contracted ebola, and you trashed Spain's healthcare system and blamed it on a systemic problem, while saying it's very unlikely to happen in the US. A few days later it happens in the US, and you jump to the defensive and shrug it off as "human error".
You don't see the problem with that?
If you believe the US is prepared to handle an ebola outbreak, you're sadly mistaken. If this thing spreads to several thousand cases, the majority of medical staff on the front lines will probably have some training 15 years ago in university, plus a 1 week refresher course to bring them up to speed, before being fired into the hospital to treat patients.
