In 2014, for instance, William A. Rutala, Ph.D., MPH, CIC, and David J. Weber, M.D., MPH, concluded that an estimated 20 percent of such infections were attributed to environmental surfaces and medical devices. Contamination of the hands of health care workers could, in turn, result from direct patient contact or indirectly from touching environmental surfaces.
Moreover, Curtis Donskey, M.D., in 2013 reviewed scientific literature and found that improving surface cleaning and disinfection reduces HAIs.”
