Prevalence of C. difficile with R 0 = 1.07 over 200 days in the model with time delay between sample collection and the release of laboratory results, without screening (a-c) and with screening (d-f) 92.5% of patients at the time of hospital admission. Curves represent the prevalence of undiagnosed colonized patients (black), and isolated patients (grey) under CDI treatment. Total prevalence is the sum of black and grey curves. The effectiveness of CDI patient isolation in preventing in-ward transmission was 100% (a, d), 90% (b, e), and 80% (c, f)
