This project is led by the ECDC Modelling team. We are grateful to the European Respiratory Virus Disease Network who contribute by collecting and reporting weekly surveillance data, and to ECDC’s Respiratory Viruses and Legionella Section who contribute by generating and providing ERVISS data, supporting interpretation of results and engaging with ECDC stakeholders. We are grateful to the ECDC Prevention and Behaviour Change team for supporting us with community engagement. Finally, we are grateful to all contributing modelling teams for their work and encourage new teams to join us in future scenario rounds, thus contributing to insights developed by ECDC and presented to ECDC's network of stakeholders and public health professionals.
