The very first thing you do when you arrive in Liberia is wash your hands in chlorine. As I learned on my recent visit to Liberia, Sierra Leone, and Guinea, the simple acts of hand-washing and bumping elbows — instead of shaking hands — quickly begin to feel normal. As the Ebola epidemic overwhelms communities and threatens livelihoods in West Africa, this change in behavior is saving lives. Today, the U.S. is helping lead a global coalition to fight Ebola with a clear strategy and data-driven approach. During my visit, I met courageous humanitarians , health workers, and community leaders who are helping turn the tide against Ebola. In fact, there are currently over 950 U.S. Government personnel on the ground in the region, and I could not be more proud of them.
