Upper‐Room Ultraviolet Germicidal Irradiation (UVGI) for Air Disinfection: A Symposium in Print

Upper‐room ultraviolet germicidal irradiation ( UVGI ) has several applications, its most important use is to reduce tuberculosis transmission in high‐burden, resource‐limited settings, especially those dealing with epidemics of drug‐resistant disease. The efficacy of upper‐room ( UVGI ) to reduce the transmission of airborne infection in real‐world settings is no longer in question. International application (dosing) guidelines are needed, as are safety standards and commissioning procedures. A recent symposium to build consensus on guidelines discussed specifications for affordable UVGI fixture designs, safety, performance, computer‐aided design ( CAD ) for UVGI , maintenance, dosimetry, gonioradiometric measurement and innovation using germicidal LED s.
