ECDC has coordinated the surveillance of diphtheria at the EU level since the transfer of DIPNET, the Diphtheria Surveillance Network, to ECDC in 2010. DIPNET used to be hosted at the UK Health Protection Agency.

  • In 2014, 30 EU/EEA Member States reported data. Nine countries reported cases due to C. diphtheriae or C. ulcerans, and 21 countries reported zero cases.
  • The majority of Member States reported data on diphtheria according to the 2008 (n=13) or 2012 (n=11) EU case definition. Five countries used an alternative or unspecified case definition. Regardless of the case definition used, only cases caused by, or with a clinical syndrome consistent with causation by, toxigenic strains are reported at the EU level (Commission Implementing Decision 2012/506/EU of 8 August 2012 of the European Parliament and of the Council).
  • All reporting countries have a surveillance system for diphtheria and reported case-based data. Clinical and laboratory-notified cases were linked at the national level and submitted to TESSy with a single record identifier. The majority of the countries reported data based on a comprehensive (n=30) and compulsory (n=29) surveillance system. For a summary of national surveillance systems characteristics by country, please refer to the Annex.
