This week, hosts Mark Masselli and Margaret Flinter reflect on 2020 at the end of a year like no other. When the COVID-19 pandemic began to take hold, they welcomed many of the world’s most renowned infectious disease, virology, and epidemiology experts. From Dr. Anthony Fauci to Dr. Ashish Jha, from New York Times writer and “Pandemic” docu-series producer Dr. Sheri Fink, to innovative scientists like Dr. Eric Topol, Dr. Zeke Emanuel, Dr. Michael Osterholm to US Surgeon General Dr. Vivek Murthy, we learned about this emerging pathogen from some of the most gifted people in health care.
