We used a WHO framework to draw attention to the core functions of health systems, specifically governance,finance, the health workforce, technology and supply management, and health-information systems (panel 1).
These interlinked functions contribute to delivery of health services.
The framework accounts for community participation in strengthening of health systems and the context in which these interactions occur.
The understanding that disease control and other priority health interventions are intrinsic to health systems is fundamental to this framework.
