And some data back from SARS: "Always wearing a mask when going out was associated with a 70% reduction in risk compared with never wearing a mask. Wearing a mask intermittently was associated with a smaller yet significant reduction in risk."
I saw a lot of people sanctimoniously talking about fit tests in normal healthcare settings as if an imperfect fit dropped effectiveness immediately down to 0% from 100%.
Yes the truth is masks help, but officials decided to lie about this to prevent panic over lack of masks. But this is damaging not only to official credibility but also to the response. A big demand for masks in January could have forced new supply chains to develop in the west. That would have averted some of the current disaster happening where hospitals can't get masks.
I think the thing is that most people will naturally treat things qualitatively. A mask either protects you or it doesn't. A substance is either a poison or it isn't. Etc.
