'Ebola is defeated', says Congolese professor who discovered virus

Ebola has been defeated. Vaccines and medical treatments have brought the deadly and terrifying disease under control, says Jean-Jacques Muyembe, the Congolese professor who first discovered the virus more than 40 years ago. The 79-year-old virologist was speaking at a ceremony in the Democratic Republic of Congo's capital Kinshasa marking the arrival on the market of the "Ebanga" treatment, which was approved last December by the US Food and Drug Administration.
