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.
