The article published in JAMA discusses a research study that examines the impact of mask-wearing on COVID-19 transmission in schools. The study, conducted in Missouri, analyzed data from 169 schools during the 2020-2021 academic year.
The findings revealed that schools with mask mandates had significantly lower rates of COVID-19 transmission compared to schools without such mandates. The study found that mask-wearing among students and staff was associated with a 3.5 times lower risk of COVID-19 outbreaks in schools. Furthermore, schools that implemented both mask mandates and improved ventilation had even lower transmission rates.
