A new research study from the centre for disease control and Prevention (CDC) has found that a mandate of wearing masks in schools plays a significant role in preventing COVID-19 cases among students. As per the CDC study, cases in children increased at a significant rate. The CDC studies pediatric COVID-19 rates from 520 counties where wearing a mask was consistent in all schools; it was applied to all schools consistently or to none of them. The CDC adjusted findings for controlling child vaccination rates for teachers and school testing data. In areas where the wearing mask was not mandatory, on average, there were 35 new pediatric cases per 100,000 children each day over two weeks of span.
