This Reporting Protocol describes data collection for influenza, COVID-19, and other respiratory viruses (such as RSV or new viruses of public health concern) in the EU/EEA and wider WHO European Region. Data collection is integrated for most datasets in line with the operational considerations for respiratory virus surveillance in Europe.
This document presents the core protocol for ECDC studies of CVE and IVE against symptomatic laboratory-confirmed influenza or SARS-CoV-2 infection, respectively, at primary care level.
