@jfeldman_epi Setting aside that it is all disingenuous antimaskism, as you demonstrate, the original premise isn't hard to understand. Community masks reduce pop-level transmission by about 25%. Mandates increase masking by some %, let's say 50% (e.g. 25%->75%)
@jfeldman\u epi抛开所有虚伪的反马斯克主义不谈，正如你所证明的，最初的前提并不难理解。社区口罩可将流行性感冒的传播减少约25%。授权会使掩蔽增加约%，比如说50%（例如，25%->；75%）
