Schools without mask mandates are more likely to have COVID-19 outbreaks, CDC finds
CBSN
The Centers for Disease Control and Prevention released new studies Friday that show enforcing masks in schools helps reduce the spread of COVID-19.
One study looked at data from schools in Arizona's Maricopa and Pima Counties after they resumed in-person learning in late July for the 2021-22 academic year. The two counties account for roughly 75% of the state's population.
The CDC found that the K-12 schools that did not have mask requirements at the beginning of the school year were 3.5 times more likely to have COVID outbreaks than schools that required all people, regardless of vaccination status, to wear a mask indoors from the first day of school.

The Trump administration deployed ICE and other Homeland Security agents to 14 of the nation's airports on Monday to help shuttle passengers through overcrowded TSA checkpoints. In one airport, the security line wait-time was up to six hours. Nicole Sganga and Kaia Hubbard contributed to this report. In:
