I’m sorry, but your linked article offers zero evidence that masks help keep transmission numbers down. The dates of analysis are when coronavirus cases were on their natural curve of decreasing cases from sheltering in place. States like California, where masks are mandated pretty much everywhere right now, are seeing cases grow daily despite mask wearing. Obviously cases will increase as people come out and this is a natural occurrence, point being, the masks are not helping us have any less cases than anyone else and they are detrimental because of how they affect blood oxygen levels. So I see this as another article pushing masks that is entirely unsupported by science.
