Abstract

Chagas disease is caused by the protozoan Trypanosoma cruzi. Although Latin America is defined as endemic, there are few studies in relation to seroprevalence of T. cruzi infection in rural areas, where the individuals do not have information on this disease. The objective was to investigate the seroepidemiology of T. cruzi in a rural human population of the city of Pelotas,  Brazil. A total of 227 individual users of a Basic Health Unit (BHU) of Cerrito Alegre, (third district of Pelotas, RS) were included in this study. Blood samples were collected and sera were tested for antibodies against T. cruzi through Chemiluminescent Microparticle Immunoassay assay and confirmation by Indirect Immunofluorescence test. The risk factors associated with the presence of the parasite were evaluated through a semi-structured questionnaire. The population evaluated had 2.7% seropositivity for T. cruzi. Among the risk factors, two were statistically different: the kind of housing (p=0.0093), with the greatest risk to live or have lived in a house of wattle-and-daub, clay, wood (OR 46.9) and the fact that the individual had been bitten by the vector (p=0.0309 and OR 14.5)
