Multiple SARS-CoV-2 transmission clusters were identified in schools in a Georgia school district, with educators often being the index cases. The Centers for Disease Control and Prevention has provided recommendations for safely opening schools.
Repeat infection with endemic seasonal coronavirus occurs commonly and raises concerns about immunity to SARS-CoV-2 as well as about the efficacy of vaccines in the protection against infection because of this virus.

The recommendation was temporarily amended to wearing surgical masks if N95s were not available, a stopgap measure that could be reversed as soon as supplies were in stock.
