Abstract

Contaminated surfaces in long-term care facility resident rooms may contribute to transmission of healthcare-associated pathogens. We demonstrated that a far ultraviolet-C light technology operated for 2 to 4 hours during periods when residents were out of the room was effective in reducing contamination of surfaces and personal items.
