Maybe because they can't find a cure for it yet.
No known cures for ebola have been found, but there is an experimental ebola drug that was given to an American doctor who contracted the disease while working with patients in Africa. The doctor survived.

Had alook around and could not find one aside from other languages.
There are many foreign scientists that have helped to influence the world around us. You can find pictures of these scientists with their inventions by doing an image search.
The spread of Ebola occurs through direct contact with an infected person. The fact that I find most intriguing is that we don't know where Ebola lives when it's not in epidemiological break-out. We have no real idea where it hides. What I think is the coolest thing is that the virus reacts with your platelets and it makes a chemical that just randomly punches holes in the capillaries and blood vessels. Because of that, it can make you hemorrhage blood from your orifices, like your nose and mouth. Or really any other orifice you can think of. Depending on the strain of Ebola 9 out of 10 people who get it die. There is no known cure for the Ebola virus.
Unfortunently there isn't yet a cure for Hutchinson-Gilford Progeria Syndrome But hopefully someday Scientists will find a cure. God bless all who have the disease.
