One Stat I heard is 92% of people ARE using masks and 72% of people with covid19 disease have used masks ....
Soooo .... 92% of the population makes up 72% of the infections, and 8% of the population makes up 28% of the infections?
On the one hand, that indicates that mask wearing is significantly associated with a reduction in the likelihood of getting the disease in the short term.
On the other hand, it also indicates that mask wearing is insufficient to prevent infection and that at best it delays the inevitable.
On the gripping hand, that kind of association is considerably weaker than the connection between race and violent crime rates, which isn't strong enough to even bring up in public discussion about crime policy.
