Health system resilience is not an inevitable byproduct of any investment in health but must be intentionally programmed and developed with necessary input, investment and contextualization. This technical product aims to guide national, subnational, and global health actors to operationalize the concept of health system resilience for advancement of universal health coverage, health security and ultimately better health for all. It supports the translation of relevant conceptual guidance and high-level recommendations into practical actions. The specific objectives are to: present a concise overview of the concept of health system resilience; provide a roadmap outlining practical and foundational steps for building health system resilience to be adapted to different contexts; share examples of actions and tools, including stakeholder roles, to support country application of the roadmap. The target audience for this work is the various stakeholders involved in strengthening health systems and public health including management of emergencies (from prevention and preparedness to response and recovery) and other public health challenges in countries. This ranges from the donors, policy-makers and decision-makers at global, national and subnational levels to the implementing institutions and line managers of health system functions and services across the health system building blocks.
