Ebola in S.A. Officials at the World Health Organization say that an outbreak of the deadly Ebola disease in the African nation of Gabon seems to be coming to an end. Twenty-six cases of the disease have been diagnosed there since July, and at least 17 people have died. As a result of the outbreak in Gabon, two cases of Ebola have been diagnosed in Johannesberg, South Africa. That has created a great deal of concern in that huge metropolitan area, though public health officials say the disease does not appear to be spreading there. NPR's Richard Harris reports.
