Our research team (epidemiologist, microbiologist and I, a naturopathic physician) compiled the largest body of research in English on the hazards of masks. Those peer-reviewed studies are at https://PDMJ.org, vol 1. The gist of what is known is that respiratory droplets are relatively large, heavy and fall quickly in front of you. The mesh of masks on the other hand aerosolize those droplets. Now those light airborne viral particles travel farther, 18 to 20 feet, and linger longer in the air. Most of that was the Duke University research we cited. But also unfiltered exhaled air shot by nozzle effect out of masks' side jets go several meters. Because a masked person incubates 100,000 bacterial colonies per hour average, you don't want to stand or sit next to those bacteria-laden side jets of a masked person.

Masked populations have shown higher rates of COVID than unmasked - county comparisons in US, thanks to Ian Miller. I write about that in 4th paper in above series. The above is my best understanding to date for why masks are neither effective nor safe.

NIH on face masks 09/25/2020

"At present, there is no evidence on the effectiveness of universal masking of healthy people in the community to prevent infection with respiratory viruses, including SARS-CoV-2. The mandatory use of masks poses some ethical questions."
