Original Note:
The CDC was stating cloth masks were not as effective as far back as Oct. 2020. This was the reason for suggesting double masking offers good virus protection. https://journals.asm.org/doi/10.1128/msphere.00637-20?permanently=true More peer-reviewed research came out in March 2021 about mask effectiveness. https://www.factcheck.org/2021/03/scicheck-the-evolving-science-of-face-masks-and-covid-19/
