Meanwhile, Samantha Power, the U.S. ambassador to the United Nations, said Friday that Ebola infections rates are expected to climb.

"In Guinea and Sierra Leone, the number of infections is projected to double every month. In Liberia, infections are projected to double every two weeks," Power said at a General Assembly session on Ebola.

Power praised countries that "have punched far above their weight." She cited the example of Cuba, "a country of just 11 million people" that "has already sent 165 health professionals to the region and plans to send nearly 300 more."
