HARBEL, LIBERIA - AUGUST 24: Workers unload medical supplies to fight the Ebola epidemic from a USAID cargo flight on August 24, 2014 in Harbel, Liberia. The U.S. government sent more than 16 tons of supplies, including anti-contamination clothing (PPE), plasting sheeting and water purification machinery. International aid agencies and the Liberian government are struggling to keep up with the rapidly-expanding epidemic. The deadly virus has killed at least 1,400 people in West Africa and more in Liberia than any other country. (Photo by John Moore/Getty Images)
