Shining a light on bacteria: Pulsed xenon ultraviolet light system just as effective as manual disinfection (VA Research Currents)

In just over 10 minutes, a pulsed xenon ultraviolet light system can disinfect a hospital room every bit as good as a human can, according to a VA study.

That’s not to say that the light, which kills common and dangerous bacteria like Clostridium difficile, methicillin-resistant Staphylococcus aureus, and vancomycin-resistant enterococci, will replace manual disinfection. Rather, say researchers, the light can supplement more traditional methods.

“There are times when surfaces are not thoroughly disinfected due to human error or because the contamination is so significant,” says Dr. Chetan Jinadatha, chief of infectious diseases at the Central Texas Veterans Health Care System in Temple, Texas.

His team’s study appeared in the American Journal of Infection Control on Feb. 10, 2015.
