UNITED NATIONS (AP) — The public health expert coordinating U.N. efforts to fight Ebola said on Tuesday that he’s heading to Washington and then to West Africa to determine the best ways the world body can support people, communities and governments affected by the deadly disease.

David Nabarro told a news conference that he will have “intensive interactions” on Wednesday with the World Bank, experts from the U.S. Centers for Disease Control and Prevention and others before flying to Dakar, Senegal on Wednesday night.
