This paper aims to discuss the political and organizational trajectory of the Health Surveillance System in Brazil. The paper is an exploratory and descriptive study, whose data were obtained through a literature review carried out in public domain databases from 1998 to 2013. The authors present a brief trajectory of the field of epidemiological, environmental and health surveillance toward a more integrated system, with case-resolution capacity. Finally, a debate was promoted on the advances and challenges of articulating proposals for organizational change and integrating practices in search of more effective responses within the scope of Health Surveillance.
