(CNN) – Dr. Tom Frieden, the director of the Centers for Disease Control and Prevention, said in a news conference Tuesday that the window to tamp down the Ebola outbreak is closing."We know how to stop Ebola, the challenge is to scale it up to stop this outbreak," Frieden said.
The world needs to support those affected countries with the outbreak because the virus is not spreading in new ways, but that speed is important because the number of cases are increasing so quickly, it will be hard to stop the outbreak.
Frieden said that he outbreak is not spreading in a new way, and the CDC and governments know how to stop it, but it is a matter of resources.
