The European Surveillance System (TESSy)


This page describes who has the right, and how to access and use data from TESSy.

Since 22 June 2021, TESSy has a new entry point through the EpiPulse platform, and will be progressively replaced by EpiPulse between 2021 and 2023.

Access to TESSy data

Types of access

  • Direct access to data: for individuals nominated by the EU/EEA countries, European Commission, EU bodies, international organisations and other entities, following the TESSy nomination procedure;
  • Access to subsets of data: for external researchers and the same group entitled to direct access (see "Requesting access to subsets of TESSy data" below);
  • Access to aggregated published data is unrestricted. Dissemination is authorised subject to appropriate acknowledgement (see Conditions for Publishing Note). See the “Surveillance Atlas of Infectious Diseases” for TESSy aggregated data.

Use of TESSy data

Access to the TESSy data, either directly or upon specific request, does not automatically imply the right to publish.

Publishing is allowed only under certain conditions and after allowing for Member States' comments when applicable. Dissemination of aggregated published TESSy data is authorised subject to appropriate acknowledgement (see Conditions for publishing note).

Requesting access to subsets of TESSy data

Subsets of TESSy data are available for research purposes, in the interest of the public health, under the conditions below to:
