In March of 2020, Mass General Brigham implemented a new policy: everyone working at the hospitals would be required to wear a surgical mask. At the time, the concept of universal masking was new and its potential effectiveness unclear. But now, a new study led by investigators from Brigham and Women's Hospital and published in JAMA makes it clear: after universal masking was implemented at Mass General Brigham, the rate of COVID-19 infection among health care workers dropped significantly.
