CDC: Masks Indoors Needed, Again

ATLANTA, GA — As the highly-transmissible Delta variant of COVID-19 solidifies its dominant status in the U.S. through a surge of cases among mostly unvaccinated people, the Centers for Disease Control and Prevention (CDC) advise masks indoors again, including schools.

“CDC recommends universal indoor masking for all teachers, staff, students, and visitors to K-12 schools, regardless of vaccination status. Children should return to full-time in-person learning in the fall with layered prevention strategies in place,” the agency announced in its new guidance to people seeking to avoid getting sick, dying or spreading the virus to their vulnerable neighbors, friends and family.

The Delta variant has quickly dominated the COVID-19 pandemic in the United States and world-wide, accounting for 83 percent of American infections.  last week, Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention, updated the estimate of the percentage of Delta variant COVID-19 infections in the U.S. during testimony before the Senate Committee on Health, Education, Labor and Pensions.

In its update about the need for masks inside again, the CDC offered the following Key Takeaways regarding school attendance when schools are scheduled to reopen in the fall.

CDC School Mask Guidance – Key Takeaways:

• Students benefit from in-person learning, and safely returning to in-person instruction in the fall 2021 is a priority.
• Vaccination is currently the leading public health prevention strategy to end the COVID-19 pandemic.  Promoting vaccination can help schools safely return to in-person learning as well as extracurricular activities and sports.
• Masks should be worn indoors by all individuals (age 2 and older) who are not fully vaccinated. Consistent and correct mask use by people who are not fully vaccinated is especially important indoors and in crowded settings, when physical distancing cannot be maintained.
• CDC recommends schools maintain at least 3 feet of physical distance between students within classrooms, combined with indoor mask wearing by people who are not fully vaccinated, to reduce transmission risk. When it is not possible to maintain a physical distance of at least 3 feet, such as when schools cannot fully re-open while maintaining these distances, it is especially important to layer multiple other prevention strategies, such as indoor masking.
• Screening testing, ventilation, hand-washing and respiratory etiquette, staying home when sick and getting tested, contact tracing in combination with quarantine and isolation, and cleaning and disinfection are also important layers of prevention to keep schools safe.
• Students, teachers, and staff should stay home when they have signs of any infectious illness and be referred to their healthcare provider for testing and care.
• Many schools serve children under the age of 12 who are not eligible for vaccination at this time. Therefore, this guidance emphasizes implementing layered prevention strategies (e.g., using multiple prevention strategies together consistently) to protect people who are not fully vaccinated, including students, teachers, staff, and other members of their households.
• COVID-19 prevention strategies remain critical to protect people, including students, teachers, and staff, who are not fully vaccinated, especially in areas of moderate-to-high community transmission levels.
• Localities should monitor community transmission, vaccination coverage, screening testing, and occurrence of outbreaks to guide decisions on the level of layered prevention strategies (e.g., physical distancing, screening testing).
