On 26 February 2021, the CDC published guidelines on ventilation in schools and childcare programs. The most important recommendations continue to be good ventilation, and wearing proper masks. Additional preventative actions include:
Consider using ultraviolet germicidal irradiation (UVGI) in schools and non-home-based childcare programs as a supplemental treatment to inactivate the virus that causes COVID-19, especially if options for increasing ventilation and filtration are limited. Consult a qualified professional to help design and install any UVGI system.
