Fifth Strategic Plan for the Development of Epidemiology in Brazil (2025-2029)

The Brazilian Association of Collective Health (Abrasco) has played a leading role in consolidating collective health in Brazil since its foundation. After 19 years, Abrasco's Epidemiology Committee resumed its planning with the development of the Fifth Strategic Plan for the Development of Epidemiology in Brazil (2025-2029). This plan emerged in a challenging context marked by social inequalities, scientific denialism, the COVID-19 pandemic, the climate crisis, and disinvestment in public policies, reinforcing the need to update Brazilian epidemiology. The plan's development occurred in multiple stages, including online surveys, debates, and in-person workshops. Workshop I (Brasília, 2023) identified priority challenges, and Workshop II (Rio de Janeiro, 2024) defined strategies to address them. The construction process was guided by the qualified participation of epidemiologists from all regions of the country and was based on principles of plurality, diversity, gender equity, and race/ethnicity. The plan highlights epidemiology across three thematic areas: education, research, and health policies, programs, and services. The Strategic Plan Working Group of the Epidemiology Committee, supported by the Secretariat of Health and Environment Surveillance of the Ministry of Health, led the process. This supplement of the Brazilian Journal of Epidemiology presents the Fifth Strategic Plan for the Development of Epidemiology in Brazil (2025-2029), contributions to the discussion of some central topics, and a deepening of strategic and operational dimensions. The Fifth Strategic Plan for the Development of Epidemiology in Brazil (2025-2029) presents a collective vision for the future, aiming to strengthen epidemiology as a central discipline within the field of collective health. It reaffirms its commitment to equity, social justice, and the consolidation of the Sistema Único de Saúde in Brazil.
