Last modified at 4/21/2016 10:15 PM by Vladimir Prikazsky


The European Surveillance System (TESSy) is a highly flexible metadata-driven system for collection, validation, cleaning, analysis and dissemination of data. Its key aims are data analysis and production of outputs for public health action. All European Union Member States (28) and EEA countries (3) report their available data on communicable diseases (49) as described in Decision No 2119/98/EC to the system.

Apart from routine surveillance, TESSy has replaced the data collection systems in place for the Dedicated Surveillance Networks (DSNs) to provide experts with a one-stop-shop for European Union surveillance data.

TESSy includes:

  • BSN      Basic Surveillance Network;
  • EISS       European Influenza Surveillance Network;
  • Enter- net       International Surveillance Network for the Enteric Infections Salmonella, Campylobacter and VTEC O15;
  • ENIVD       Network for Diagnostics of "Imported" Viral Diseases (ENIVD;
  • ESSTI       European Network for STI Surveillance;
  • EU-IBIS        European Invasive Bacterial Diseases Surveillance Network;
  • EuroHIV       European HIV/AIDS Surveillance Network;
  • EuroTB       European Tuberculosis Surveillance Network;
  • EARSS       European Antimicrobial Resistance Surveillance Network;
  • IPSE       Improving Patient Safety in Europe (hospital acquired infections;
  • DIPNET        European Diphtheria Surveillance Network;
  • EWGLINET       European Legionnaires’ Disease Surveillance Network;
  • ESAC       Surveillance or Antimicrobial Consumption;
  • EUVACNET       European Surveillance Network for Vaccine Preventable Disease;
