ABIDJAN, Ivory Coast (AP) — International donors have failed to deliver $1.9 billion in promised funds to help West African countries recover from the Ebola epidemic that killed more than 11,000 people and decimated already weak health care systems, the U.K.-based charity Oxfam said Sunday. Oxfam called on donors and the governments of Sierra Leone, Liberia and Guinea — the three hardest-hit countries — to provide detailed information on how aid is being provided. Originating in Guinea more than two years ago, the Ebola outbreak left some 23,000 children without at least one of their parents or caregivers, while some 17,000 survivors are trying to resume their lives despite battling mysterious, lingering side effects.
