EU level surveillance of COVID19

For EU level surveillance, ECDC requests EU/EEA countries and the UK to report laboratory-confirmed cases of COVID-19 within 24 hours after identification. This should be done through the Early Warning and Response System (EWRS).

ECDC and the WHO Regional Office for Europe – in collaboration with their surveillance networks in the Member States – are coordinating the rapid reporting of data as requested in the WHO case reporting form.

Case reporting forms will be collected using The European Surveillance System - TESSy.
