There is something fishy going on with this mess for sure. Who in their right mind would allow these individuals to return? Smoke and mirrors..
It's no more contagious than the aids virus, so that's a crock. You have to physically contact BODILY FLUIDS with a cut to contract it. Fear is no excuse to deny the best help possible for those who risk all to help others. Denying them help is frankly, inhuman.
I suspect they are trying to get more doctors to volunteer to contain this outbreak before it goes global. Abandoning infected doctors in Africa probably wouldn't help this.
