Clostridium difficile infection is a major source of illness in the United States (1). Population-based estimates of its incidence tend to include only subsets of infections defined by the setting of C. difficile acquisition (2–4) or are from patient populations outside the United States (5–9). These studies (2–9) offer useful data for control measures but do not help clinicians and policy makers understand the population-based incidence of C. difficile infection. To determine the incidence of C. difficile infection during 2007, we estimated the incidence of C. difficile infection among members of 2 Kaiser Permanente health plans and extrapolated our incidence estimate to the US adult population.
