From what I see, if I’m not mistaken, the first nurse went to the ER Friday night, and ebola was confirmed Saturday. It seems like, then, Vinson would have already left. Up until that point, it had been maintained that precautionary measures were adequate so that health care workers who took care of him were at low risk. I have seen confirmed that they were under no restrictions but self-monitoring. So how many of the other 70 or so probably self-quarantined and stopped going places like the theatre, out to dinner, the grocery store, or taking their children to activities, especially without having symptoms, although it’s indeed quite possible that some did have some but what they had turned out to be a cold or flu? Even if someone did develop some symptoms, they would likely think, before Pham’s case, that it wasn’t ebola. Perhaps Amber Vinson was less cautious than she knew she needed to be, and/or than other workers who cared for Duncan, but right now there isn’t enough known to say that.
Self monitoring for suspected Ebola would include not spreading it. And we’re talking about a professional nurse. Who was entrusted by the board of nursing to care for the general public in this way
