The key points from data available in 2015 are:

;
• After a peak in 2008, the incidence of CDI in the last few years is relatively stable (despite a slight increase in 2013). The incidence is lowest in Flanders and highest in Wallonia.

;
• There is a decline in the severity of CDI and in the number of deaths attributed to CDI

;
• There is a large variation in the incidence of CDI between hospitals, which may indicate an important potential for prevention

;
• There is a large diversity of ribotypes identified by the reference laboratory, which illustrates the diversity of sources of transmission. The most notable trend is the decline in the hypervirulent ribotype 027.
