Introduction
Respiratory infections pose a significant health risk to older adults residing in long-term care facilities (LTCFs). Seasonal outbreaks of influenza, respiratory syncytial virus (RSV), and other respiratory viruses frequently lead to hospitalizations and increased mortality among this vulnerable population. While traditional infection control measures such as hand hygiene, vaccination, and surface cleaning remain cornerstone practices, airborne transmission of pathogens represents a critical yet often under-addressed vector in LTCFs. To confront this challenge, germicidal ultraviolet (GUV) light technology—which has demonstrated effectiveness at inactivating airborne viruses in controlled environments—has garnered attention as a potential adjunctive intervention in these settings.
