An American infected with the deadly Ebola virus is being closely monitored in a hospital in Atlanta, home to the Centers for Disease Control. A second American aid worker, also infected, is expected to arrive soon.

The two were working with American charities at an Ebola treatment center in Liberia when they contracted the virus. And their transfer back to the U.S. has caused a lot of concern and questions about how the decision was made to bring Ebola to American shores for the first time in history.

Doctor Ford Vox, journalist and physician based at Shepherd Center in Atlanta, joins Take Two to talk more about this. He teaches at Emory University Hospital, where these patients are being treated.
