U.S. doctor risks life to fight Ebola

The American doctor infected with Ebola speaks out.

In a statement, Doctor Kent Brantly said: "As my treatment continues in the isolation unit at Emory University Hospital, I am recovering in every way... There are still a few hurdles to clear before I can be discharged, but I hold on to the hope of a sweet reunion with my wife, children and family in the near future."

The deadly virus, though, is still spreading. The World Health Organization says there are now more than two thousand cases of Ebola in West Africa and more than 1,100 deaths.

They say these numbers "vastly underestimate" the magnitude of the outbreak, which they expect to go on for some time.

But help is on the way. One American doctor is risking her life, traveling to the center of the outbreak to help fight's the spread of this deadly disease.
