A Centers for Disease Control and Prevention (CDC) study found that schools in two Arizona counties that didn’t require universal masking were 3.5 times more likely to endure COVID-19 outbreaks than schools with mask mandates.
Out of the 191 schools in Maricopa and Pima counties that experienced outbreaks by the end of August, 59.2 percent did not have a mask requirement, compared to 8.4 percent that required masks from the start of the school year.
Almost a third of outbreaks occurred in schools that implemented mask mandates after the school year began.
The results support the argument to require masks in schools to reduce transmission, at a time when the controversial debate has turned political and bled into ongoing court battles. […]
The CDC also released an additional study on masking in schools, finding that counties with school mask mandates experienced lower increases in pediatric COVID-19 case rates than counties without school mask requirements.
