CNN is also learning new details about the Dallas nurse, Nina Pham, who is infected with Ebola. In interview with CNN's Erin Burnett, her close friend and former colleague Jennifer Joseph said Pham was wearing a full hazmat suit when treating Duncan.

So how was she able to contract the deadly virus?

The director of the CDC today admitted the agency could have done more to prevent Pham from contracting the virus:

"I wish we had put a team on the ground the day the first patient was diagnosed. That may have prevented this infection," Dr. CDC Director Tom Frieden said.
