I have been a bit baffled by the messaging on mask wearing in the US. No, surgical masks are not 100% effective, but neither is 6 ft distance, washing your hands when you get home, etc. The main benefit for the general population is to prevent spread from asymptomatic people. https://twitter.com/zeynep/status/1240269572781072384
