One major goal of the Centers for Disease Control and Prevention (CDC) is to help prepare the public for emerging health threats. What is the status of public health emergency preparedness at the federal, state and local levels? What progress has been made in preparing our country for natural, biological, chemical and other hazards? And in the context of progress, where is there room for improvement? Dr. Richard Besser, pediatrician and director of the CDC's Coordinating Office for Terrorism Preparedness and Emergency Response, addresses these questions and more with host Dr. Jennifer Shu.
