You are assuming that people are wearing the masks correctly, and that they are not re-using them. This is simply not the case. Most people are wearing their favorite masks for days and weeks at a time, like a fashion accessory. A swab of any of them would likely turn a Petri dish into a jungle. And on top of that, the masks are not even fitted properly. Having the majority of the public wearing masks has only helped to deprive the medical community of the resource. It has done close to nothing to protect the wearers.
Bullshit.
Watch this.

excatly. the mask protects the other person from you. The mask doesn’t protect you. The video should show the person with the mask inhaling the dust cloud and seeing the dust go around the mask into the persons mouth. Unless the mask is sealed air tight around your face it will not protect the wearer. wear a shop mask. The exhale is controlled but the inhale stops p95%.
