The Conversation: Evidence shows that, yes, masks prevent COVID-19 – and surgical masks are the way to go. “I’m an assistant professor of environmental health sciences. I, too, have wondered about the answers to these questions, and earlier this year I led a study that examined the research about which materials are best. Recently, I was part of the largest randomized controlled trial to date testing the effectiveness of mask-wearing. The study has yet to be peer reviewed but has been well received by the medical community. What we found provides gold-standard evidence that confirms previous research: Wearing masks, particularly surgical masks, prevents COVID-19.” I have mentioned this study before but this article goes deep into it.
