(CNN) -- "It's even worse than I'd feared," Dr. Tom Frieden, director of the Centers for Disease Control and Prevention, said Wednesday of the Ebola outbreak rampaging through West Africa. "Every day this outbreak goes on, it increases the risk for another export to another country.
"The sooner the world comes together to help Liberia and West Africans, the safer we will all be."
