This document discusses Brazil's 22-year experience developing its national health system, known as SUS, towards the goals of universality, comprehensiveness, and equity. Key aspects include establishing health as a right in the 1988 constitution, decentralizing the system to municipalities, expanding primary care through family health teams, and ongoing challenges around sufficient and stable financing. The SUS now provides universal coverage through tax-funded public services and regulated private partnerships, showing progress on health access, outcomes, and inclusion over decades of implementation.
