In a new interview with Ian Bremmer for GZERO World, former US Surgeon General Vivek Murthy discusses how Florida went from a relatively low number of cases to the epicenter for the outbreak. Dr. Murthy says many states where cases are currently climbing did not heed "the lessons that we learned from New York." In this portion of the interview, Murthy also discusses new therapies and treatments that are helping the most severely ill. The complete interview begins airing on public television stations across the US on Friday, July 24. Check local listings and visit gzeromedia.com for more.
