A pilot project was carried out to investigate the feasibility of HIVDR surveillance in EU/EEA countries and to make recommendations for the design and implementation of a potential future HIVDR surveillance system at the European level.
Influenza epidemics occur every winter with high impact on disease burden, hospitalisations and excess mortality in countries in the WHO European Region. To understand the characteristics of circulating influenza viruses during seasonal epidemics, virological influenza surveillance is performed and detected viruses are further characterised at national influenza centres (NICs) that are part of the wider network of the WHO Global Influenza Surveillance and Response System (GISRS). External quality assessments (EQAs) are important instruments in assessing the quality of the generated data that are reported nationally and internationally through The European Surveillance System (TESSy).
