Abstract
This text aimed to analyze characteristics and challenges of the 16th Brazilian National Health Conference based on the conference three thematic axes: Health as a right; Consolidation of the Brazilian Unified Health System (SUS) principles; Adequate and enough funding for SUS. Given the initiatives to dismantle the social security model and the setbacks of social protection policies, to delimitate health in an expanded sense is essential to defend the SUS project. We analyzed the proposal of Universal Health Coverage as an alternative to universal systems. We then presented the restrictions of universal coverage and how the restrictions can threaten the SUS principles. We also discussed insufficient SUS funding and possible worsening in the face of fiscal austerity policies. To strengthen social participation and to monitor the proposals approved at the conference are necessary.
