There are reports circulating that colleges, hospitals, and some officials have started to reimplement COVID-19 mask mandates, although hospitalizations still remain relatively low.

Atlanta’s Morris Brown College announced on social media this week that it is reimplementing its mask mandate over what it said was an increase in positive COVID-19 cases among students at the Atlanta University Center. The college also said it would mandate isolation and quarantine regimens under Centers for Disease Control and Prevention (CDC) guidelines as well as contact tracing.

“All students and employees are required to wear face masks (staff may remove in their offices while alone),” the announcement said.

The college also told students to maintain “physical distancing” and said there will be no large student gatherings or parties for the next two weeks. It will also mandate students and employees to get their temperatures checked when they arrive at the campus.
