Healthcare System Overview

Brazil has a dual healthcare system. The public Sistema Unico de Saude (SUS) provides universal, free healthcare to all residents funded by taxes — about 80% of Brazilians rely solely on SUS. However, long wait times and capacity constraints drive about 26% of Brazilians (~51 million people) to also hold private health insurance ('planos de saude'), which provides duplicate coverage with access to private hospitals and shorter wait times. Over 80% of privately insured Brazilians access coverage through their employer.
