The U.S. National Institutes of Health (NIH) announced on March 10, 2022, schools in the U.S., with mandatory masking during the SARS-CoV-2 Delta variant surge, had approximately 72% fewer cases of in-school virus transmission of the SARS-CoV-2 virus.

This study, funded by the NIH, included more than 1.1 million students and over 157,000 staff attending in-person school across nine states.

The authors pointed out that their study was conducted when Delta was the dominant variant.

Therefore, their study did not obtain data on school masking in preventing the spread of the Omicron variant.

However, they added that masking remains a critical preventive measure in times with high community infection rates.

As of March 10, 2022, the U.S. CDC confirmed about 98% of the U.S. population is in a location with a low or medium COVID-19 Community Level.
