EU surveillance

For EU level surveillance, EU/EEA Member States and the UK report the number of laboratory-confirmed cases of COVID-19 every 24 hours through the Early Warning and Response System (EWRS).

Additional enhanced surveillance has been established through The European Surveillance System - TESSy.
ECDC and the WHO Regional Office for Europe – in collaboration with their surveillance networks in the Member States –  coordinate the reporting of:

  1. Enhanced case-based data on probable and confirmed COVID-19 cases with a  focus on hospitalised cases (recordtype: NCOV)
  2. Aggregated data on the number of tests performed; sentinel outpatients testing; and testing of severe acute respiratory infections (recordtype: NCOVAGGR)
  3. The transmission status at NUTS2 level according to the WHO transmission classification (recordtype: NCOVCLASSIFICATION)

Data should be reported to TESSy weekly (every Wednesday by 12:00 noon) for all recordtypes.

The entries (coded values and descriptions) for reporting can be found in the TESSy metadataset:
