Authoring Committee: Photobiology Committee
The IES Photobiology Committee prepared this Committee Report in response to the COVID-19 pandemic, to explain germicidal ultraviolet (GUV) disinfection. The report provides answers to frequently asked questions on GUV and its abilities, with some limitations, to safely reduce the transmission of SARS-CoV-2, the virus that causes COVID-19. The report is focused on the potential uses of GUV in healthcare facilities. It distinguishes GUV air and surface disinfection usages, and it emphasizes the need for GUV to be applied correctly and monitored for output and safety, and that training on the operation and maintenance of the systems over time is also important. The document also provides safety precautions regarding residential use.
