CAESAR is the only pan-European surveillance network monitoring antimicrobial resistance (AMR) outside the EU/EEA. Covering countries and areas across the WHO European Region that are not part of EARS-Net, the surveillance network coordinated by the European Centre for Disease Prevention and Control (ECDC), CAESAR generates essential data to support national policies and strengthen AMR response efforts. As part of the Global Antimicrobial Resistance Surveillance System (GLASS), CAESAR bridges regional and global efforts to address AMR.
A joint initiative of WHO/Europe, ESCMID, and the Dutch National Institute for Public Health and the Environment (RIVM), CAESAR advances AMR surveillance through collaboration, scientific expertise, and data-driven insights.
