CDC Recommends UVGI for Ventilation in Schools and Childcare Programs

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:

1. Bring in as much outdoor air as possible.
   Use child-safe fans to increase the effectiveness of open windows.
   Consider having activities, classes, or lunches outdoors when circumstances allow.
2. Ensure Heating, Ventilation, and Air Conditioning (HVAC) settings are maximizing ventilation.
   Make sure your ventilation systems are serviced and meeting code requirements. They should provide acceptable indoor air quality, as defined by ASHRAE Standard 62.1
3. Filter and/or clean the air in your school or childcare program. 
   Improve the level of air filtration as much as possible
   Consider portable air cleaners that use high-efficiency particulate air (HEPA) filters

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.
