While the concept of health system resilience is supported by a rapidly growing knowledge base, there remains an unmet need and demand for its measurement and monitoring as part of sustainably strengthening health systems and building resilience at country level. This package of health system resilience indicators (HSR indicators) addresses this gap, complementing the body of experiences and resources identified in the Health Systems Resilience Toolkit and supporting implementation of the recommendations in WHO’s position paper on building health system resilience for universal health coverage and health security. The added value of this package includes bringing together what health systems require to be functional during periods of relative normalcy, in the face of day-to-day challenges and stressors, sometimes referred to as “everyday resilience,"  as well as what is needed when there are small or large shocks.
