The European Surveillance System (TESSy)- Surveillance Unit
• Support strengthening of national surveillance systems
• Establish EU-wide standard case reporting
• Monitor trends of diseases across Europe to provide a rationale for public health actions in MS
• Disseminate the results to stakeholders for timely public health actions at EU and MS level
• Coordinate the integrated operations of the Dedicated Surveillance Networks

The European Surveillance System (TESSy)- Starting point
• List of 47 notifiable diseases + AMR+ nosocomial infections
• 17 dedicated surveillance networks (DSNs):• Cover 20 diseases (+ 3 not on the list)
• 27 Member States + 3 EEA/EFTA with their own surveillance systems• Mandatory, voluntary• Population based, sentinel• Data from laboratories, physicians, hospitals• Case-based, aggregated• Sometimes more than one system per disease per country

Impact for member states
• Huge workload• Different interfaces
for data upload• Different database

Impact for DSN hubs• Data cleaning
effort for all member states
• Feedback for all member states
