What scientists know about COVID-19 -- and what they don't
How much do we know about COVID-19, the virus spreading misery across the globe? Dr. Siddhartha Mukherjee joins Jeffrey Brown to discuss understanding the dynamics of the virus within people it has infected, why some experience much more severe forms of illness than others, how we can limit asymptomatic transmission and the need to buy medical researchers time to develop treatments.
