Face Masks for the General Public | Royal Society DELVE Initiative
Face masks could offer an important tool for contributing to the management of community transmission of Covid19 within the general population. Evidence supporting their potential effectiveness comes from analysis of: (1) the incidence of asymptomatic and pre-symptomatic transmission; (2) the role of respiratory droplets in transmission, which can travel as far as 1-2 meters; and (3) studies of the use of homemade and surgical masks to reduce droplet spread. Our analysis suggests that their use could reduce onward transmission by asymptomatic and pre-symptomatic wearers if widely used in situations where physical distancing is not possible or predictable, contrasting to the standard use of masks for the protection of wearers. If correctly used on this basis, face masks, including homemade cloth masks, can contribute to reducing viral transmission.

This takes a lot of guts, I’m impressed:
May 1st was my last day as a VP and Distinguished Engineer at Amazon Web Services, after five years and five months of rewarding fun. I quit in dismay at Amazon firing whistleblowers who were making noise about warehouse employees frightened of Covid-19.
