From the CDC;
The following public health efforts provide additional layers of COVID-19 prevention in schools:
Testing to identify individuals with SARS-CoV-2 infection to limit transmission and outbreaks
Vaccination for teachers and school staff, and in communities, as soon as supply allows
Health Equity Considerations
The absence of in-person educational options may disadvantage children from low-resourced communities, which may include large representation of racial and ethnic minority groups, English learners, and students with disabilities. Plans for safe delivery of in-person instruction in K-12 schools must consider efforts to promote fair access to healthy educational environments for students and staff. Thus, essential elements of school reopening plans should take into account the communities and groups that have been disproportionately affected by COVID-19 infections and severe outcomes. Schools play a critical role in promoting equity in education and health for groups disproportionately affected by COVID-19.
Essential Elements of Safe K-12 School In-person Instruction
Mitigation strategies to reduce transmission of SARS-CoV-2 in schools
Regardless of the level of community transmission, all schools should use and layer mitigation strategies. Five key mitigation strategies are essential to safe delivery of in-person instruction and help to mitigate COVID-19 transmission in schools:
Universal and correct use of masks
Handwashing and respiratory etiquette
Cleaning and maintaining healthy facilities
Contact tracing in combination with isolation and quarantine, in collaboration with the health department
Schools providing in-person instruction should prioritize two mitigation strategies:
Universal and correct use of masks should be required, at all levels of community transmission. Require consistent and correct use of face masks, by all students, teachers, and staff to prevent SARS-CoV-2 transmission through respiratory droplets.
Physical distancing (at least 6 feet) should be maximized to the greatest extent possible. To ensure physical distancing, schools should establish policies and implement structural interventions to promote physical distance of at least 6 feet between people. Cohorting or podding is recommended to minimize exposure across the school environment.
