    Masks can prevent COVID-19


    Critics of the requirement to wear masks point out that there is a lack of relevant randomized clinical trials that randomly assign participants to a control or intervention group


    "This should really be the end of the debate," said Ashley Styczynski, an infectious disease researcher at Stanford University in California, who was a co-author of the preprint describing the experiment


    Styczynski and her colleagues first developed a strategy to promote the wearing of masks, and adopted measures such as health workers reminding people to wear masks in public places


    The team found that the number of symptomatic cases in the treatment village was lower than that in the control village


    Material difference

    The study linked surgical masks to an 11% reduction in risk, compared with a 5% reduction in cloth risk


    Neither the laboratory findings nor the mask test findings have been peer reviewed


    How COVID is changing human behavior


    The results of this study prompted Monica Gandhi, an infectious disease physician at the University of California, San Francisco, to stop wearing cloth masks


    In Bangladesh and other low- and middle-income countries, masks will remain a particularly important line of defense, where people cannot get vaccines
