A public health system encompasses the network of public, private, and voluntary organizations and individuals that work collectively to deliver essential public health services and promote the health of populations within a jurisdiction.
This system includes a wide range of partners, such as:
Governmental public health agencies (state, local, tribal, and national levels)
Healthcare providers and systems (hospitals, clinics, community health centres)
Public safety and emergency services
Human services and charitable organisations
Educational and youth development organisations
Community-based and faith-based organisations
Recreation, arts, and environmental agencies
Economic and philanthropic institutions
The public health system functions collaboratively to prevent disease, improve access and service consistency, respond to public health emergencies, and ensure the conditions for people's health. It operates under a shared framework that values partnerships, prevention, and population-level health outcomes.
