Dario Gonzalez, left, a medical director with the International Organization for Migration and a native of New York City, explains to Maj. Uzoma Aniniba, a Denver native, and the operations officer for the 36th Engineer Brigade, how the health care workers will archive the patients records electronically, after the grand opening ceremony of the Ebola treatment unit near Buchanan, Liberia, Dec. 22, 2014, as part of Operation United Assistance. This method is used to keep from destroying patient records. Operation United Assistance is a Department of Defense operation in Liberia to provide logistics, training and engineering support to U.S. Agency for International Development-led efforts to contain the Ebola virus outbreak in western Africa.
