In 1999, we performed serological and entomological surveys to evaluate the impact of vectorial control measures against transmission of Chagas' disease in the endemic area of Mambaí and Buritinópolis (GO). A census was undertaken of the population, after which the entomological survey was performed regarding the dwelling units and serological evaluation of the human population. Blood samples were collected by digital puncture in filter paper. The first serologic test performed to detect antibodies against Trypanosoma cruzi was the indirect immunofluorescence test (IFI) with (1/2)0 positive dilution as cut-off point and, positive samples were further evaluated with indirect hemagglutination reaction (HAI). The prevalence of positive IFI reactions was 12.3% (95%CL: 11.5-13.2). Triatoma infestans was not found within the dwellings. The absence of infection among individuals younger than 14 years and, the absence of T. infestans during the last entomological survey demonstrates the success of the control program of Chagas' disease in the studied area where the vectorial transmission can be considered to have been interrupted.
