Dr. David Fisman has been at the forefront of the battle against infectious diseases, from SARS to COVID-19. We asked him about this new virus in January, and he got it wrong. He was far from alone in that. The nature of discovering new diseases is making hypothesis based on what's known, and then adjusting as new data becomes available.

But in a world where we are held to our predictions or told not to flip-flop our positions, that nuanced approach can be mistaken for failure. Today, Dr. Fisman joins us again to walk us through everything we've been wrong about since COVID-19 emerged, how new discoveries have informed our approach and what we could still be wrong about as we plan for the months to come.

GUEST: Dr. David Fisman, professor of epidemiology, Dalla Lana School of Public Health
