Efficacy of manual cleaning and an ultraviolet C room decontamination device in reducing health care–associated pathogens on hospital floors

Published:January 04, 2018DOI:
      Recent studies suggest that floors may be an underappreciated source for transmission of health care–associated pathogens. However, there are limited data on the effectiveness of current cleaning and disinfection methods in reducing floor contamination. We demonstrated that manual postdischarge cleaning by environmental services personnel significantly reduced floor contamination, and an automated ultraviolet C room disinfection device was effective as an adjunct to manual cleaning.
