Surveillance and study protocols

ECDC provides technical guidance to the Member States. This includes guidance for the implementation of monitoring systems for specific groups vulnerable to COVID-19, a methodology for estimating the prevalence of SARS-CoV-2 in the population, and support to timely reporting of key information on COVID-19 epidemiology in EU/EEA Member States and the UK.

The following technical guidance is available:

The TESSy reporting protocol for COVID-19 contains guidelines on how to prepare data for submission to TESSy, lists all deadlines, and points out recent changes to the reporting metadata.

Coronavirus disease 2019 (COVID-19) Contact Tracing Reporting Protocol, Version 1

Technical report -

This reporting protocol describes the collection of data regarding contact tracing. The data collection aims to help assess the effectiveness and efficiency of contact tracing operations, to provide information on transmission of SARS-CoV-2, and to provide contextual information on the progression of the pandemic to tailor response measures.

Publication

COVID-19 surveillance guidance - Transition from COVID-19 emergency surveillance to routine surveillance of respiratory pathogens

Technical report -

This publication offers practical guidance to EU/EEA countries, encouraging them to transition from emergency surveillance for COVID-19 to more sustainable, objective-driven, surveillance systems.

Data collection on COVID-19 outbreaks in closed settings with a completed vaccination programme: long-term care facilities, version 2.0

Technical report -

The main aim of this activity is to collect information on the severity of breakthrough COVID-19 infections in outbreaks at long-term care facilities (LTCFs) and to obtain a timely estimate of vaccine effectiveness in these settings, by SARS-CoV-2 variant and vaccine product.

Publication

Guidance for representative and targeted genomic SARS-CoV-2 monitoring

Technical report -

This document offers practical guidance for EU/EEA Member States on implementing genomic SARS-CoV-2 surveillance. It also includes advice on how to estimate the number of sequenced samples needed to achieve various objectives, including the early detection of novel variants.

Publication

European surveillance of COVID-19 in long-term care facilities in the EU/EEA: aggregate data reporting - Surveillance protocol version 1.1

Technical report -

This surveillance protocol seeks to enable countries to report their existing national surveillance data on COVID-19 in LTCFs easily and regularly. This will enable ECDC to report national trends in the EU/EEA, with the aim of providing all EU/EEA countries with timely information to support their preparedness activities for LTCFs.

Publication

Methodology for estimating point prevalence of SARS-CoV-2 infection by pooled RT-PCR testing

Technical report -

The methodology presented in this document provides a way to efficiently estimate COVID-19 prevalence by analysing the results of pooled RT-PCR tests, without the need to identify individual test results. The statistical foundation of the methodology is explained in detail.

Publication

Surveillance of COVID-19 in long-term care facilities in the EU/EEA

Technical report -

ECDC has worked with EU/EEA countries to develop a methodology for regular national reporting of existing national surveillance data on COVID-19 in LTCFs, aiming for maximum feasibility. This is to enable ECDC to communicate timely information on epidemiological trends of COVID-19 in LTCFs, in support of national and EU/EEA-level preparedness and response activities.
