Cape Town, Ramadan 26, 1436 AH, July 13, 2015 SPA -- Africa's Ebola outbreak has not run its course and around 30 people are still getting infected each week, the United Nations' special envoy for the deadly disease, David Nabarro, said on Monday, Reuters reported. Under normal circumstances, such an infection rate would be considered "a major, major outbreak," he said. "Probably about one third of these people are not coming from the contact list, which means they are surprise cases, and that's a big worry," Nabarro told a conference organised by the World Health Organization in Cape Town. The worst recorded outbreak of Ebola has already killed more than 11,200 people across West Africa. -- SPA 12:36 LOCAL TIME 09:36 GMT www.spa.gov.sa/w
