Another study found similarly close rates of infection for mask vs no mask: https://www.acpjournals.org/doi/10.7326/M20-6817 https://www.acpjournals.org/doi/10.7326/M20-6817 From this CDC report we can see that despite widespread mask usage there is infection(as we are seeing in general) https://www.cdc.gov/mmwr/volumes/69/wr/pdfs/mm6936a5-H.pdf https://www.cdc.gov/mmwr/volumes/69/wr/pdfs/mm6936a5-H.pdf Each of these studies have their own issues such as small sample sizes and self reporting.
