Quadripartite guidance on One Health integrated surveillance of antimicrobial resistance and use

The Quadripartite guidance on One Health integrated surveillance of antimicrobial resistance (AMR) and antimicrobial use (AMU) provides a practical framework for countries to design and strengthen surveillance systems that connect human, animal, and environmental health. It outlines how to tailor systems to national goals and resources, covering data collection, sampling strategies, laboratory and epidemiological requirements, and methods for data analysis, sharing, and communication. The aim is to generate reliable, comparable insights across sectors and countries to better inform policy and action. Intended for policymakers, public health authorities, and technical experts, the guidance is a “living document” that will evolve as new evidence and needs emerge.
