The incidence of CDI, as well as deaths attributable to C difficile, has also risen in Europe and Canada. In Canada's Estrie region of Quebec, the incidence quadrupled in 2003 to 92.2 cases per 100,000 population. In a survey of 97 hospitals across 34 European countries, the incidence of C difficile in hospitalized patients was 41 per 100,000 patient-days. [33]

The worldwide increased incidence of CDI has been attributed to a variety of risk factors, including more elderly patients in the population, treatment resistance to fluoroquinolones, and the emergence of a newly discovered, more virulent strain of C difficile (BI/NAP1/027). [34] Additional risk factors toward increasing CDIs include the use of penicillins and clindamycin, as well as an increased use in the total number of antibiotics in the community. [34]
