The world's largest outbreak of Ebola, which began earlier this year in Guinea, has spread to Liberia and Sierra Leone, killing over 670 people in West Africa. With no vaccine and no cure, the virus is deadly for up to 90 percent of those infected. Two U.S. aid workers are now being treated for the virus in Liberia. And on Sunday, Liberia announced it's shutting most of its border crossings after an infected man flew from there to Nigeria. We discuss the Ebola epidemic and the challenges in treating and containing it.
