“At this critical juncture when COVID-19 is resurging,” wrote Centers for Disease Control and Prevention director Dr. Robert Redfield in a Journal of the American Medical Association editorial published on Tuesday, “broad adoption of cloth face coverings is a civic duty, a small sacrifice reliant on a highly effective low-tech solution that can help turn the tide favorably in national and global efforts against COVID-19.”…

“Like herd immunity with vaccines, the more individuals wear cloth face coverings in public places where they may be close together, the more the entire community is protected,” Redfield and his co-authors wrote. “Community-level protection afforded by use of cloth face coverings can reduce the number of new infections and facilitate cautious easing of more societally disruptive community interventions such as stay-at-home orders and business closings.”
