Operational Strategy for K-12 Schools through Phased Mitigation

https://www.cdc.gov/coronavirus/2019-ncov/downloads/community/schools-childcare/K-12-Operational-Strategy-2021-2-12.pdf

1. Consistent implementation of layered mitigation strategies to reduce transmission of SARS-CoV2 in schools
2. Indicators of community transmission to reflect level of community risk
3. Phased mitigation and learning modes based on levels of community transmission

"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

• Universal and correct use of masks
• Physical distancing
• Handwashing and respiratory etiquette
• Cleaning and maintaining healthy facilities
• Contact tracing in combination with isolation and quarantine, in collaboration with the health
department

"in-person instruction should prioritize:
1. Universal and correct use of masks should be required, at all levels of community transmission.
"consistent and correct use of face masks, by all students, teachers, and staff"

2. Physical distancing (at least 6 feet)"
"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."

• Families of students who are at increased risk of severe illness (including those with special healthcare needs)
or who live with people at increased risk should be given the option of virtual instruction regardless of the mode of learning offered.

"Aerosol Science"
Building Ventilation and cleaning the air.

I fully agree.
