• 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
