I'm not sure as to why you state the opposite but I have numerous family members that are nurses and I agree with the above poster.
		
		
	 
And I have a wife who is a nurse - an infection control manager who has been distinguished numerous times as nurse of the year, nominated for Western NY nurse of the year, a bunch of other awards, etc., and I yelled to her to ask her.  That was about 15 minutes ago; she went on and on and on and on and on and on.    No, it's not almost over in Africa.  Still considered "widespread transmission" in Sierra Leone, Liberia, and Guinea.  
http://www.cdc.gov/vhf/ebola/outbreaks/2014-west-africa/distribution-map.html   They're still bringing patients over to the US for treatment.  (*gasp* That doesn't make headlines any more.)   The Dallas transmission from patient to nurse was due to an overzealous protocol which turned out to increase hazards more than it decreased them - they used duct tape over the gown/glove and gown/neck area.   During removal, while it decreased the possibility for transfer during care, it increased the probability while removing the duct tape.  The protocols have been gone over, again and again and again and again.   At least in NY, every hospital has bent over backwards; I know my wife has spent untold hours making sure emergency personnel (ambulance crews, etc.) have been trained, etc.  
It's not going to spread in the US, period.  If for some reason, we had an influx of infected passengers who came here at the same time, there's a very slim possibility that someone could screw up the protocol during treatment, but that would be hard to do - before and after you treat a patient, there's another staff member with a checklist going over, step by step, exactly which steps you're supposed to take next for personal protection.  At least in NY, every hospital has had to run drills.   When I use my wife's phone to call someone that's not programmed into my cell phone, I scroll past a bunch of different contacts.  Someone named EBOLA in capital letters.  Not sure where that one goes to.  
But, again, from an expert in this, not a typical RN who you might happen to know and who would never be in contact with an Ebola patient, even if there was one, no, Dallas isn't going to happen again.
