Scare in the air: Flight passengers urged to get tested for tuberculosis

Passengers on a U.S. Airways flight over the weekend were told they had been exposed to tuberculosis. When the plane landed in Phoenix, paramedics came on board and removed one passenger. Everyone else on board was advised to get tested for TB. So how concerned should these passengers be? How concerned should you be next time you fly? Anderson discussed this with Chief Medical Correspondent Dr. Sanjay Gupta.
