The vast majority of the studies were published in 2020. Where are the hundreds of studies published prior to 2020 on mask efficacy and why were they not used? 115 studies primarily done in 2020 after mask mandates leads to a biased conclusion.

I am all for wearing masks, but I don't understand why the article talks about spreading COVID-19 by breathing. From the NIH: "Droplet transmission occurs by the direct spray of large droplets onto conjunctiva or mucous membranes of a susceptible host when an infected patient sneezes, talks, or coughs."

Some better clarity, please. The CDC website does not state that COVID-19 is spread when we "breathe" -- only "when an infected person coughs, sneezes or talks" and only if "these droplets can land in the mouths or noses of people ...nearby or possibly be inhaled into the lungs," From the CDC website: "The virus that causes COVID-19 is thought to spread mainly from person to person, mainly through respiratory droplets produced when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs. Spread is more likely when people are in close contact with one another (within about 6 feet).
