121 - Checking in with Dr. Justin Lessler and What We Now Know—And Still Don't—About COVID-19

This week, we're checking in with guests we interviewed earlier in the pandemic. Today, Dr. Josh Sharfstein gets an update from infectious disease epidemiologist Dr. Justin Lessler who was one of our very first podcast guests. Back in March, there were a lot of unanswered questions. Lessler talks about what we now know about transmission and fatality rates and what questions remain, what needs to happen in the short term to get cases under control, and what might be a truly transformative innovation in the fight against COVID-19.
