Only on the "CBS This Morning" podcast, CBS News contributor Dr. Tara Narula explores the public health and global policy implications of the coronoavirus epidemic with global health expert Laurie Garrett and expert on Chinese domestic and foreign policy, Elizabeth Economy. Garrett, a Pulitzer Prize-winning science writer, explains how the outbreak compares to other crises like the SARS outbreak in 2003.
