My issue is that this "cure" appeared recently and from my (admittedly layman's) perspective, it hasn't had enough time to prove it's completely effective. And given the risks involved if someone is wrong, it seems foolhardy to just trust that it will work.
And when I read that the doctors are "stumped" as to why the disease wasn't completely eliminated, it scares the hell out of me. This isn't AIDS. It's faster and far more easily and casually contracted. Not to be trifled with. Until people have been truly "Ebola free" and not contagious for years, I think precautions are warranted.
