The effect of ultraviolet-C technology on viral infection incidence in a pediatric long-term care facility.

•This study represents the first demonstration of the effect of an ultraviolet-C (UV-C) disinfection device on viral infection rates.•UV-C technology implementation was associated with a 44% reduction in viral infection incidence rates among pediatric patients in a long-term care facility over a 12-month period.•The results suggest that UV-C technology is a potentially important component of eliminating the environment as a source of viral infections.
