In Reply We thank Crobach and colleagues for their thoughtful comments on our article.1 They raise pertinent questions regarding the mechanisms through which the detection and isolation of C difficile carriers on hospital admission could lead to a decrease in Clostridium difficile infection (CDI) rates. They suggest 3 potential mechanisms: a decrease in the progression from carriage to disease; a decrease in spread from carriers; and a decrease in spread from patients with CDI. It is difficult to ascertain which of these mechanisms may have contributed to the decrease in CDI rates in our hospital.
