Is there any good evidence that masks work to slow the spread of Covid? I've seen lots of evidence that they do not work, in which case they do not signify what

  >Is there any good evidence that masks work to slow the spread of Covid? Plenty of evidence to that effect can be found with a simple Google search, some of which is presented here, without further discussion. https://www.pnas.org/content/118/4/e2014564118 https://www.pnas.org/content/118/4/e2014564118 https://www.cdc.gov/coronavirus/2019-ncov/science/science-briefs/masking-science-sars-cov2.html https://www.cdc.gov/coronavirus/2019-ncov/science/science-br... https://med.stanford.edu/news/all-news/2021/09/surgical-masks-covid-19.html https://med.stanford.edu/news/all-news/2021/09/surgical-mask... https://www.kxan.com/news/coronavirus/do-face-masks-work-here-are-49-scientific-studies-that-explain-why-they-do/ https://www.kxan.com/news/coronavirus/do-face-masks-work-her...

    Interesting to consider this analysis [0] of available studies that mentions some if the CDC references. The overall quality of the supporting evidence for masks seems to be not very good. In light of the societal costs if, in fact, they do nothing, I would hope for a stronger signal of their efficacy. It seems particularly cruel to mask children, who do not seem to have adverse outcomes with Covid, if the masks don't work.
