State Department Encouraging Embassy Staff To Leave Liberia

The State Department has told families of U.S. Embassy staff in Liberia to leave because of the Ebola outbreak. The department says it made the decision after an assessment from its medical office. It says there's a lack of routine health care services at major hospitals. The head of the Centers for Disease Control and Prevention, Tom Frieden, says the next few weeks will be critical to ending the virus' spread.
