Will screening for Ebola at airports work?

The CDC says more than 94% of travelers entering the U.S. from West African countries impacted by Ebola travel through five airports. They are in New York, Newark, Washington, Chicago and Atlanta. New screening measures are about to go into effect at those airports. There are already questions about whether these precautions will work. Anderson discussed it with former CDC disease detective Dr. Seema Yasmin and Dr. Irwin Redlener, who is the Director of the National Center for Disaster Preparedness.
