English: A health care worker attending the Department of Defense Ebola Treatment Training Team’s class at the National Police Training Academy, Paynesville, Liberia, recovers after encountering an expert patient trainer who simulated a suspected Ebola patient who becomes confused and aggressive during his stay at an Ebola treatment unit, Dec. 23, 2014. The trainers use tomato paste and water to simulate bodily fluids during the life-like scenarios. The title, expert patient trainer is a title used only for Liberians who are Ebola survivors and who role play as patients for the course. The DET-3 is scheduled to make a critical transition of its mission back to the World Health Organization, the ETU health care workers who were trained as trainers, and PAE, a contracting company, Jan. 1, 2015. The WHO, which created the course in conjunction with the Liberian Ministry of Health, has been conducting the same training since September 2014. The DET-3, as part of Joint Forces Command – United Assistance, conducted 14 classes at the NPTA while its mobile training team conducted 12 other classes in remote areas across Liberia, training more than 1,500 health care workers. 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.
