(2021, March 12). 12 March 2020 “The public could be putting themselves more at risk from contracting coronavirus by wearing face masks.” “Jenny Harries, England’s deputy chief medical officer, said the masks could ‘actually trap the virus’ and cause the person wearing it to breathe it in” https://t.co/ar5kOOxih3 [Tweet]. @YearCovid. https://twitter.com/YearCovid/status/1370307577888698369

    1. ReconfigBehSci {@SciBeh}. {2021-03-04] there will be many a wrong analysis as we cycle through the 1 year anniversary and there is nothing to mark this one out as uniquely bad, but what does seem surprising to me in hindsight is the confidence with which people pronounced given that this was a new disease.[Tweet}, Twitter.

    1. Take away: Though not a guarantee of health, wearing masks reduces the number of respiratory infections compared to no/inconsistent mask wearing.

      The claim: Masks are protective against clinical respiratory illness.

      The evidence: The authors performed a meta-analysis of random controlled trials and observational studies examining mask use in health care workers. The results showed that wearing masks resulted in fewer infections compared to people without masks. These results agree with other publications (1, 2). One pre-print article which performed meta-analysis showed inconclusive results concerning the effectiveness of masks (3). Based on these meta-analyses, mask wearing results in fewer respiratory infections, though it will not prevent all infections when used as the sole protective measure.

    1. CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies) especially in areas of significant community-based transmission.

      It sounds like it's recommended because a significant portion of people with coronavirus are asymptomatic or pre-symptomatic, and the virus can spread through speaking, coughing or sneezing.

    1. we wear cloth face masks because they protect other people from getting COVID-19 from us, in case we have it and don’t know.

      There's no "proof" that these work, but there's a hope that it helps along with hand washing and a distance of six feet.
