The organisation's medical mission in Liberia, West Africa, was one of only two medical NGOs active in Liberia during the beginning of the 2014 Ebola outbreak. Samaritan's Purse and SIM USA both have been actively engaged in treating the recent outbreak of Ebola hemorrhagic fever in Liberia. On August 1, 2014, the organisation announced that it was evacuating 60 nonessential personnel from Liberia. Dr. Kent Brantly, a Texas-based doctor working for the organisation, was the first U. S. Citizen to contract the Ebola virus in Liberia while treating the disease. He arrived in the United States on Saturday, August 2, and was treated and subsequently released after nearly three weeks in a special isolation unit of Emory University Hospital in Atlanta, Georgia. The organization recorded their mission in Liberia in the documentary Facing Darkness. Samaritan's Purse also operates aircraft in support of its humanitarian relief efforts including a Douglas DC-8-72CF jetliner and a converted Douglas DC-3 featuring turboprop engines.
