Virus Outbreak Update: Neil deGrasse Tyson and Laurie Garrett

When a fan asks Neil deGrasse Tyson why there aren't more outbreaks, virus expert Laurie Garrett sets the record straight about two terrifying virus outbreaks: H7N9 influenza that caused havoc in China and killed 25% of the people who got it, and MERS-CoV, or Middle Eastern Respiratory Syndrome Coronavirus, that is genetically close to SARS. With the start of mass pilgrimages to the area happening right now, MERS is a serious concern to the worldwide health community. With comic co-host Chuck Nice.
