My fear is that we're not able to stop a simple stomach flu which is spread almost the same way, through bodily liquids, so I don't think it will be easy to stop once it hits first world countries like most people currently assume...
And to the point, we've never successfully "beat" GI because the stakes were never this high.
It is easily spread by sick people touching things (eg handle bars in the tube) which you then touch, before touching something that goes into your mouth. If Ebola came to the uk without major changes in behaviour it would likely infect millions of active, young people via London.
