Dallas hospital’s handling of Ebola a failure?

(CNN) – There are ongoing questions regarding the Dallas hospital that treated Thomas Duncan for Ebola, and is currently caring for the 26-year-old nurse infected with the deadly disease, Nina Pham.

Texas Health Presbyterian Hospital – where Duncan eventually died of Ebola – initially sent him home when he first came to the hospital with a fever. Pham contracted the disease while treating Duncan.

Former Dallas County Medical Society president Dr. Robert Haley defended the hospital, saying the staff did a "terrific job" caring for Duncan.

"The mortality of this disease is anywhere from 60 to 70% and it's unclear how many people can be saved. So the fact that this patient died is not a failure, in fact he was doing pretty well until the very end," said Haley.

And yet the hospital's handling of Ebola cannot be called a success.
