The concept of equity in the Unified Health System (SUS) is essential for ensuring a fair distribution of resources and health opportunities, taking into account the specific needs of different population groups. Equity goes beyond universal access to healthcare services, encompassing the adaptation of these services to address socioeconomic, geographic, and cultural inequalities. In SUS, this means providing additional support to vulnerable populations, such as low-income individuals, residents of remote areas, and groups with cultural and linguistic barriers. Key challenges include regional disparities, such as inadequate healthcare infrastructure in rural and peripheral areas, and socioeconomic inequalities that hinder access due to indirect costs and lack of information. To overcome these challenges, SUS should adopt comprehensive strategies, such as increasing funding and resources for underserved areas, implementing public policies that address socioeconomic inequalities, and investing in transportation and health education. Inclusion is equally crucial, requiring the removal of physical and social barriers, the promotion of a culture of respect and cultural competence among healthcare professionals, and the active participation of diverse groups in policy formulation. Furthermore, promoting interinstitutional collaboration, community participation, and the collection and analysis of disaggregated data to guide targeted policies is important. These strategies aim to create a fairer and more inclusive health system, capable of adequately serving the entire Brazilian population
