Except that the two patients brought home have responded so well to the treatments we DO have, that one of them is seeking to return to Africa and to his ministry. Both of them have officially been treated to the point that the disease in in remission.
I do not think you are factoring in what this would do to an immunocompromised individual.
Mortality rates in a developed nation are still going to be pretty high (10-20 percent most likely). Treatment is entirely supportive - IV fluids, and antibiotics that aren't designed to treat this illness. Antibiotics which Ebola may become resistant to in time.
No one knows what this would look like in a patient that is immunocompromised, diabetic, or simply overweight and out of shape.
And those two patients could return because they are the two people in the world that we know definitively
are immune, since they just lived through it. I wouldn't draw any conclusions about the level of risk from such a small sample size though.
