Probably one of the best things about ebola, IMO, is that it is so virulent that it won't just sit as a quiet pool of infectious people though. Unlike reistant TB etc.
That could possibly change as Ebola gets more comfortable in this new host it has occupied. It is not in it's best long term interests to kill us off so quickly. From what I understand, it has already been rolling the dice quite a bit...
Since Ebola can be transmitted via sperm, you have to wonder what might be going on in there with the changes being made. Kind of scary to think that a pandemic of Ebola would not only be mutating itself, but also mutating us as well. -> http://www.scientificamerican.com/article/virus-genes-human-genome/
