The Brazilian Health System, known as SUS (Sistema Único de Saúde), is a publicly funded healthcare system that provides universal access to medical services for all citizens. Established in 1990, it aims to ensure that everyone receives necessary healthcare, regardless of their financial situation. The system is funded through taxes and offers a range of services, including preventive care, hospital treatment, and specialized services. SUS operates at three levels: primary, secondary, and tertiary care. Primary care focuses on basic health services and prevention, while secondary care includes specialized services and hospital care. Tertiary care involves advanced medical treatment and complex procedures. The system emphasizes equity, aiming to reduce health disparities across the population.
