Surveillance of antimicrobial resistance in Europe, 2024 data

This executive summary sets out results derived from 2024 antimicrobial resistance (AMR) data, sourced from invasive isolates reported to both the Central Asian and European Surveillance of Antimicrobial Resistance (CAESAR) network and the European Antimicrobial Resistance Surveillance Network (EARS-Net).

EARS-Net amassed data from 30 countries, encompassing the whole of the European Union/European Economic Area (EU/EEA) while CAESAR received reports from 14 countries from the remainder of the WHO European Region. EARS-Net and CAESAR use compatible methodologies for data gathering and analysis.
However, given that each national surveillance system is shaped by country-specific protocols and practices,
it is important to exercise caution when comparing AMR patterns between countries.
