At the very beginning of the pandemic, there was lots of uncertainty about the primary transmission route of COVID-19. Increasingly, the evidence is showing the virus spreads through the air.

Why did it take scientists so long to determine that this? What do we know now about airborne transmission of SARS-CoV-2 and is it possible to create indoor environments so that schools and businesses can be open safely? How should journalists cover this aspect of the story as President Biden is pushing to reopen schools for in-person learning in March and many state governors are allowing businesses to increase the number of people permitted indoors at the same time?

Hear from two experts on this topic: one an expert on how infectious diseases spread in the air, and the other an infectious disease epidemiologist and hospital preventionist.
