JOHANNESBURG, Muharram 26, 1436, November 19, 2014, SPA -- The World Bank now expects the impact of the Ebola epidemic on Sub-Saharan Africa's economy to be around $3-$4 billion, well below a previously outlined worst-case scenario of $32 billion, the bank's chief economist for the continent said on Wednesday, Reuters reported. "The risk of the highest case of economic impact of Ebola has been reduced because of the success of containment in some countries. It has not gone to zero because a great level of preparedness and focus is still needed," Francisco Ferreira said in Johannesburg. --SPA 12:59 LOCAL TIME 09:59 GMT www.spa.gov.sa/w
