Clostridium difficile: an update on its epidemiology and role in hospital outbreaks in England and Wales.
Data from the surveillance system of general outbreaks of infectious intestinal disease and from laboratory reports collated by the Communicable Disease Surveillance Centre (CDSC) and requests for outbreak investigation by the PHLS Anaerobe Reference Unit were used to evaluate the current epidemiology of Clostridium difficile infection in England and Wales. Between January 1992 and December 1996, CDSC received 10,220 laboratory reports of C difficile isolation from patient's faeces and 26,873 of toxin in faeces. Over 75% of all reports were of people aged 64 years and over. The surveillance system captured a minimum data set on 694 hospital outbreaks of infectious intestinal disease. C. difficile was responsible for 109 (15%) outbreaks affecting 1625 people, of whom 1152 were found to have a C. difficile toxin producing strain. The median duration of outbreaks was 11 days. Fingerprinting by Pyrolysis Mass Spectrometry (PMS) was performed by the PHLS Anaerobe Reference Unit in 60 outbreaks, and typing by Polymerase Chain Reaction ribotyping (PCR) in 14.
