A multisectoral, One Health approach is necessary to address complex health threats at the human-animal-environment interface. Since 2017, FAO-WHO-WOAH have developed and piloted the Joint Risk Assessment Operational Tool (JRA OT) - an implementation tool associated with the Tripartite Zoonoses Guide. The JRA OT was designed to support countries in applying a consistent and harmonized approach to assessing risks posed by zoonotic disease hazards.

Between 2018 and 2020, the JRA OT was piloted in 19 countries in all six WHO regions, and this included two regional training of trainers in Senegal and Tunisia. Following iterative refinement and improvement, the JRA OT offers decision-makers and technical experts a 10-step approach to create a system for conducting joint qualitative risk assessments. Results of the JRA OT are used to support policy communication, risk mitigation, and improved planning and preparedness for zoonotic diseases, contributing to health security at the national, regional, and global levels.
