This report which is part of the RAGIDA project (Risk Assessment Guidance for Infectious Diseases transmitted on Aircraft) provides viable options for decision-makers when faced with the choice of whether to contact trace air travellers and crew that were potentially exposed to infectious diseases during a flight.

This document outlines operational considerations for how to support the continuity of national influenza surveillance systems and public health laboratories for the epidemiological and virological surveillance for influenza in the 2020–2021 season during the ongoing COVID-19 pandemic.

This publication presents the core European protocol for a series of proposed influenza vaccine effectiveness studies. The protocol includes a proposed plan for pooled analysis and has recently been adapted to measure vaccine effectiveness for the pandemic vaccine in 2009-10. Together with its twin publication ‘Protocols for cohort database studies to measure influenza vaccine effectiveness in the EU and EEA Member States’, this publication covers all methodological issues in the design and implementation of vaccine effectiveness studies, both for seasonal and the new A(H1N1)v influenza.

This document presents a menu of possible public measures to be taken during influenza pandemics, giving public health and scientific information on what is known or can be said about their likely effectiveness, costs (direct and indirect), acceptability, public expectations and other more practical considerations. The ‘ECDC Menu’ aims to help EU Member States and institutions, individually or collectively, decide which measures they will apply.
