Did he die? That is the major difference. The patient is super, super contagious when dying, which is also when they need the most hands on care.
Also, the other patients were transferred in from one hospital to another - with the receiving hospital knowing they were arriving, and having a plan, protection, etc. In Dallas, he just walked in the door, unannounced. Did they blow it by not admitting and isolating him soon enough. Yes. But, no one in the US expected an Ebola patient to just show up on the doorstep - even if he had walked into Emory or the hospital in Omaha things might have played out in a similar fashion.
We were all lulled into a false sense of security, believing that the only cases that would arrive here would be US healthcare workers who would be transported securely every step of the way, with no chance of their coming into contact with anyone who was not prepared. No one, at any hospital, expected patients to just show up at the door, unannounced. We were told that the likelihood of that happening was miniscule, and not worth worrying about.
