One reference is not like the other. Take your pick: > "However, according to medical historians, the decline in deaths from influenza in San Francisco can be partly attributed to the mandatory mask-wearing policies." From a social science piece published in May 2020, https://www.thelancet.com/action/showPdf?pii=S0140-6736%2820.... The full quote is "Yet in cities like San Francisco, the decline in deaths from influenza was partly attributed to the mandatory mask-wearing policies." It contains no further attribution or references. > "A study then in 1919 concluded that mandatory mask mandates did not make any difference on epidemic, while observing that a likely reason for their ineffectiveness was that masks were worn outdoors and not inside in gatherings when conditions for transmission would be greatest. It also noted that most masks were improperly constructed of inadequate materials." Comes from an actual medical study by the California Board of Health, published in 1919. https://babel.hathitrust.org/cgi/pt?id=uc1.31378008030317&vi... |
