Some studies suggest ultraviolet light, including UVC and pulsed xenon UV, effectively reduces microbial contamination and hospital-acquired infections, while other studies indicate limited impact on specific pathogens like Clostridioides difficile and vancomycin-resistant Enterococci.
Ultraviolet (UV) light has been widely studied for its disinfection properties and its potential role in public health. UV light, particularly in the UV-C spectrum, has been shown to inactivate a variety of pathogens, making it a valuable tool for environmental disinfection in healthcare settings and beyond.

UV light, particularly in the UV-C spectrum, is a powerful tool for disinfection and public health. It is effective in inactivating a wide range of pathogens and has been successfully implemented in healthcare settings to reduce infection rates. However, its use should be complemented with traditional cleaning methods and other environmental controls to ensure comprehensive disinfection. Alternative UV light technologies, such as 405 nm violet-blue light, offer additional options for continuous disinfection in occupied environments.
