@Nutmeg031992 @ramzmom0996 @kprather88 @CDCDirector @CDCgov @AbraarKaran It's unlikely.
There are several empirical studies suggesting that 100% mask use reduces spread by about 25%. Since this is a mix of various (mostly crappy) masks, more effective masks has to be more significant.
That doesn't make it "end the pandemic" though.
@肉豆蔻031992@ramzmom0996@kprather88@cdcdcedirector@CDCgov@AbraarKaran不太可能。
有几项实证研究表明，100%使用口罩可以减少25%左右的传播。由于这是一个混合了各种（大多是蹩脚的）面具，更有效的面具必须更重要。
但这并不意味着“结束大流行”。
