United Nations Secretary-General Ban Ki-moon said the situation for returning health workers from Ebola-affected countries is proving difficult and that the stigma against them should end, AP reported. Ban spoke Monday on a trip to Ethiopia, where he called health workers managing the Ebola outbreak in West Africa "exceptional people." Ban said the world depends on health workers to fight Ebola. -- SPA 21:17 LOCAL TIME 18:17 GMT تغريد
