Clostridium difficile associated disease (CDAD) becomes a notifiable disease under the Acute Infectious Gastroenteritis Disease (AIG) category, from May 4th 2008


The Department of Health and Children has recently communicated to the HSE that Clostridium difficile (toxin producing) should be notifiable under the category of “Acute Infectious Gastroenteritis (AIG)”.

Notification of CDAD under the disease category of acute infectious gastroenteritis (AIG) is an interim measure until the specific disease and its related organism, Clostridium difficile (toxin producing), is specified on the Infectious Diseases Regulations schedule of notifiable diseases.

Beginning on the week commencing 4th May 2008, all medical practitioners or clinical directors of diagnostic laboratories are asked to notify all cases of Clostridium difficile – associated disease (CDAD) as per amended AIG case definition, to the relevant Department of Public Health.  All new events of CDAD will be entered onto the national Computerised Infectious Disease Reporting (CIDR) system and weekly reports will be produced by HPSC and made available on the HPSC website
