Dr. Sanjay Gupta goes inside the CDC's Ebola war room

The Ebola outbreak has the CDC's Emergency Operations Center on high alert. The center's director described the crisis in Western Africa as the biggest and most complex Ebola outbreak in history. He also says that it can be stopped. Chief Medical Correspondent Dr. Sanjay Gupta went inside the CDC for a first hand look at how Ebola is being tracked and monitored.

There are serious ethical questions being raised about the treatment of the two Americans infected with Ebola. They were flown back to the U.S. and given an experimental serum that is credited with helping them fight the disease. Some people are contrasting that to the situation in Africa, where patients are left in squalor and the death toll continues to rise. Anderson discussed the controversial treatment with Art Caplan, the director of the Division of Medical Ethics at New York University's Langone Medical Center.
