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 LEDs.
