  Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been a pandemic threat worldwide and causes severe health and economic burdens. Contaminated environments, such as personal items and room surfaces, are considered to have virus transmission potential. Ultraviolet C (UVC) light has demonstrated germicidal ability and removes environmental contamination. UVC has inactivated SARS-CoV-2; however,

According to CDC, Ventilation interventions can help reduce the number of infectious viral particles (e.g., SARS-CoV-2) in the air. Ventilation interventions include opening windows, using fans, adding high-efficiency particulate air (HEPA) fan/filter systems, and adding upper-room ultraviolet germicidal irradiation (UVGI). This factsheet presents information on upper-room UVGI, which can be effective at reducing exposures to
