Operational considerations for respiratory virus surveillance in Europe

This document outlines operational considerations to support the continuity of national surveillance systems and public health laboratories for epidemiological and virological surveillance for influenza, SARS-CoV-2, and potentially other respiratory viruses (such as RSV or new viruses of public health concern) in the 2022/2023 winter season and beyond. It builds on previously published documents on COVID-19 and influenza surveillance.
