As students returned Sunday to Morris Brown College, a small Atlanta-based historically Black college, the university announced it would be imposing a two-week mask requirement as well as a ban on large gatherings following “reports of positive cases among students in the Atlanta University Center,” Fox 5 News Atlanta reported earlier this week.

California-based hospitals owned by Kaiser Permanente in California and two Upstate Medical University facilities in Syracuse, New York, have also reimposed mask mandates. And in Kentucky, the Lee County School District canceled classes for two days this week and switched to remote learning amid a recent outbreak of COVID, strep throat, and the flu, the AP reported.
