RESUMO
A new conglomerate family sample of 194 dwellings with 996 resident persons were studied in the town of Barcelos, State of Amazonas, in order to re-evaluate the risk of Chagas disease. During the survey the persons were interviewed and in this occasion we showed to them a collection of Panstrongylus, Rhodnius and Triatoma, asking if they recognized and eventually have been bitten by this kind of bugs. At this time we collected 500 ul of blood in microtainer® tubes from 886 interviewed persons who gave permission after informed consent. A screening test for T. cruzi antibodies based on agglutination of colored polymer particles, sensitized with three different synthetic peptides of T. cruzi (ID-PaGIA Chagas Test)®, showed 13.2 percent of sera positivity, but only 6.8 percent were confirmed by indirect immunofluorescence, and ELISA with purified T. cruzi antigens. Two hundred and six interviewed persons (20.7 percent) recognized the triatomines, as "piaçavas' lice" and 62 (30 percent) confirmed that have been bitten by the bugs, 25.8 percent of them had a positive serology for T. cruzi infection. Electrocardiographic alterations were shown in 9.3 percent of the seropositives and in 11.9 percent of the seronegative cases. This was considered not statistically significant
