Here is an article by a surgeon on the effectiveness of masks: https://www.meehanmd.com/blog/2020-07-22-if-masks-dont-work-then-why-do-surgeons-wear-them/

Working in the hospital (a controlled environment) is not the same thing as everyday life such as commuting on the transit. The studies of masks were conducted in labs which are controlled environments. Many European countries have nation-wide mask mandates but covid cases still continue to rise.

Indeed. Did you read the article? The surgeon totally debunks the efficacy of masks. Good for surgeons in a controlled environment...totally the WRONG thing to do for a pandemic.
