President Obama announced on Wednesday that the United States was withdrawing almost all of its troops from the fight against Ebola in West Africa, but he said the world needed to remain vigilant as it sought to eradicate the deadly disease. "While our troops are coming home, America's work is not done," Mr. Obama told an audience that included six Ebola survivors. "Our mission is not complete. Today we move into the next phase." The president said that civilian employees of various government agencies, along with American volunteers and about 100 members of the military, would remain in West Africa as the effort moved from containment of the virus to eradication.
