Evaluation of germicidal ultraviolet-C disinfection in a real-world outpatient health care environment.

Background: The coronavirus disease 2019 pandemic has highlighted the need for effective infection control in outpatient health care settings. Germicidal ultraviolet-C (GUV) light, known for inactivating microorganisms by damaging their deoxyribonucleic acid or ribonucleic acid, offers a potential solution. This study examines the efficacy of GUV air disinfection systems in real-world outpatient environments.

Ultraviolet-C mediated inactivation of Candida auris, a rapid emerging health threat.

Health care-associated infections, particularly those caused by multidrug-resistant organisms (MDROs), pose significant challenges to patient safety. Candida auris (C auris), an emerging MDRO fungus, has been acknowledged as an urgent threat by the Centers for Disease Control and Prevention due to its high mortality and difficulty in prevention, diagnosis, and treatment. In this study, we investigated the efficacy of 254 nm ultraviolet-C light (UV-C) in inactivating C auris on hard surfaces.
