Dr. Tom Frieden, Director of the U.S. Centers for Disease Control and Prevention, carefully removes his PPE as he exits the ELWA 3 Ebola treatment Unit. Through each step of this process, staff from Médecins Sans Frontières/Doctors Without Borders (MSF) decontaminate his equipment with a chlorine/water solution. MSF operates the ELWA 3 ETU, which opened on August 17. Photographer: Athalia Christie
