The Worst Ebola Outbreak Ever

Ebola was first discovered in 1976 — a virus that first causes flu-like symptoms that quickly evolve into vomiting, diarrhea and both external and internal bleeding. As many as 90% of those infected in previous outbreaks have died. Now Guinea, Sierra Leone and Liberia — three of the world’s poorest countries — are in the midst of the worst epidemic so far. At least 670 people have died; more than 1000 others have been infected, including doctors and other medical personnel.
