Chagas disease still constitutes an important medical problem in affected countries. In some, the extent of the disease is still unknown and control programs have not been implemented. In others the disease has been reduced due to regular control programs and other economic and social factors. Epidemiological surveillance with community participation to guard against disease transmission is now the basic challenge. Applied research and in-depth reformulation of health systems are required to establish efficient and sustainable Chagas disease surveillance programs, considering low density of peridomiciliary vectors as the most relevant factor. In addition, a large population of already infected, poor individuals require specific medical attention and social security. As a consequence of health care decentralization, Federal institutions such as the Brazilian National Health Foundation (FNS) are being progressively decommissioned, and new participants must be engaged in the process. Communities themselves, together with regional and local institutions, must take charge of surveillance in order to guarantee its efficiency and sustainability.
