A population-based spatio-temporal analysis of Clostridium difficile infection in Queensland, Australia over a 10-year period

There was an increasing annual trend in CDI in Queensland from 2003 to 2012. Peaks of CDI were found in summer (December-February), which is at odds with the current epidemiological pattern described for northern hemisphere countries. Epidemiologically plausible explanations for this disparity require further investigation.
