Mask mandates and onsite dining bans reduced COVID infections

United States // 06 March, 2021

Infection and death rates rose over the past year in US counties that did not have mask requirements, or where on-site dining was reopened, per a study by the Centers for Disease Control and Prevention (CDC.) Indoor and outdoor dining both increased the cases. Researchers looked at data on cases and deaths reported on a county level between March and December last year. They were examining how those figures are associated with mask mandates and restaurant dining.

Counties that opened restaurants for on-premises dining saw infections increase about six weeks later, and deaths increase two months later. On-premises dining at restaurants, indoors or outdoors, was associated with rising case and death rates 41 to 80 days after reopenings. Infections and deaths both declined after counties mandated masks. Mask mandates were linked to statistically significant decreases in coronavirus cases and death rates within 20 days of the order.

The authors state, "Mask mandates and restricting any on-premises dining at restaurants can help limit community transmission of COVID-19 and reduce case and death growth rates."CDC Director, Dr. Rochelle P. Walensky, said, "We would advocate for policies, certainly while we’re at this plateau of a high number of cases, that would listen to that public health science."
