“In our systematic review, we identified 10 RCTs [randomized controlled trials] that reported estimates of the effectiveness of face masks in reducing laboratory-confirmed influenza virus infections in the community from literature published during 1946–July 27, 2018. In pooled analysis, we found no significant reduction in influenza transmission with the use of face masks…”
“We did not find evidence that surgical-type face masks are effective in reducing laboratory-confirmed influenza transmission, either when worn by infected persons (source control) or by persons in the general community to reduce their susceptibility…”
Some have said "If masks work, everything should be 100% opened. If they don't work, then the mask mandates should be repealed."
In Asian nations, and in mega-cities in the US (NYC, LA, etc) with virtually 100% compliance for months, should not the numbers be decreasing with the mask mandates, instead of increasing? Since they are increasing, it should be obvious that the masks don't work, after being in use since this past spring. Thus, the mandates should end. When you compare to countries and states that don't have a mask mandate, there is no significant difference in similar sized cities. If the masking worked, shouldn't the regions with the mandates be significantly lower than those that don't, as opposed to insignificant, or even higher?
