The European Surveillance System (TESSy)- Surveillance Unit
• Support strengthening of national surveillance systems

• 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)
