Thus the obvious problem for authorities — given Coronavirus particles are far smaller than smoke particles (see comparison above — a coronavirus is on the left) then these mandated cloth masks offer even less protection against them. The CDC itself said as much in the early days of Cv-19, so why the change of mind? Is it all about control of people, not the virus?
That may seem like a logical conclusion, but empirical evidence suggests otherwise. Including a recent study in Kansas
Kansas counties that had a mask mandate had a 50% reduction in the spread of COVID-19 when compared to those without, according to a study by the University of Kansas Institute for Policy and Social Research. Mandates don’t affect people’s mobility. BY UNIVERSITY OF KANSAS INSTITUTE FOR POLICY AND SOCIAL RESEARCH

To be meaningful any scientific experiment needs to be repeated multiple times and results verified from the same method. The obvious problem here is that if a person is infectious with any droplet borne virus and cloth masks are so porous, a lot of droplets are still going to make it through. At the time the cv-19 flap began the advice was if you need to sneeze then sneeze into your elbow. But it seems droplets make it out just from speaking. The thin but solid plastic visor type shields are going to be more effective than cloth masks, if you’re really worried. They will cost more but not a lot.
