FIG 5.

Control rooms. Pie charts represent the amount of positive C. difficile findings (red) compared to negative findings (gray). The sum of red and gray portions per pie chart represents the number of total sampled sites in different rooms on high-touch surfaces in patient rooms (A), trap stagnant water and biofilms in patient en suite bathrooms (B), sampled sites related to the washer disinfectors and bedpans in soiled workrooms (C), and sink trap stagnant water and biofilms in soiled workrooms (D). The floor plans are for illustrative purposes only and do not necessarily correspond to the actual room layout.
