A Tale of Two Masks Studies

Last week, we featured two prominent scientists on the topic of COVID-19. Two studies were mentioned: the Duke mask study, examining the efficacy of different kinds of masks in a physics laboratory, and the recently-release Danish mask study (DANMASK) – the largest controlled study of masks since the beginning of the pandemic.

This week, I am joined by lead researchers on each study – Dr. Eric Westman of Duke University, and Dr. Henning Bundgaard of the University of Copenhagen.

Creon Levit and Dr. Nick Cozzi also return to offer their commentary.
