    With dozens of researchers at Yale, Stanford, Berkeley and IPA and several other organizations, we ran a cluster randomized trial involving almost 350,000 people and 600 villages in Bangladesh to assess the impact of community masking on COVID.

        We conducted an intervention that increased mask-wearing by 29 percentage points using the techniques described here:https://mobile.twitter.com/jabaluck/status/1392879291185119233?lang=en …

        We ran a massive randomized controlled trial investigating many different strategies to get communities of people to wear masks -- we're now scaling up the strategies that worked in many regions throughout South Asia. https://twitter.com/poverty_action/status/1392650983092768769 …

        With this 29 percentage point increase in mask-wearing, we saw a 9% drop in serologically confirmed COVID.

        The reduction was larger in villages where we (randomly) used surgical masks than those where we used cloth masks; in surgical mask villages, we saw a 12% reduction in COVID overall and a 35% reduction among those aged 60+.pic.twitter.com/qnvqTcSqBD

        Since severe morbidity and mortality are concentrated among the elderly, this suggests that community-wide masking can be an extremely effective tool to combat COVID.

        If going from 13/100 to 42/100 people wearing masks leads to reductions of the magnitudes above, near universal mask-wearing (as is possible with enforced mandates in some areas) might lead to substantially larger reductions.

        As noted, we find especially convincing evidence that surgical masks are effective. Cloth masks reduce COVID symptoms, but the effect we find on symptomatic infections (confirmed via blood tests) is driven by surgical masks.

        Cloth masks are likely better than nothing, but surgical masks or masks with higher filtration efficiency should be preferred to cloth masks where available.

        In subsequent posts, which I'll link here when available, I'll say more about how our study fits into the existing literature, as well as caveats and policy implications.

        Some follow-ups: I should note that the PIs on this project were myself and @mushfiq_econ (economists at Yale), @Kwong_Laura, Steve Luby and Ashley Styczynski, epidemiologists and environmental scientists at Stanford (and in Laura's case, now Berkeley!).

        The bottom-line is that, as of March 2020, we had RCTs showing effects in hospitals for medical masks, lab evidence suggesting masks were effective as source control for related viruses, and suggestive cross-country evidence for COVID https://twitter.com/Jabaluck/status/1243675541913440256 …

        In summary, the average value of masks as a policy to counter COVID remains high in the US, especially in places where deaths and severe morbidity remain high, where vaccination rates are low, or where caseloads are growing.
