What does “The Science” say about the efficacy of masks in specific situations?
The CDC and NIH have been ignoring the sciences of fluid flow, filtration, and anything else mask related since some politician thought that the masks worn in Korea and Taiwan had something to do with their early success in avoiding COVID outbreaks.
I'd like to see the "science" about the effectiveness of all of the public health efforts taken since the beginning of the COVID-19 outbreak. Lets do thinks like compare Sweden's results with England's results, or look for any correlation between mask mandates in the USA and actual rates of infection in counties with outbreaks.
