Chagas disease (CD) is considered a neglected disease by the World Health Organization and requires priority from the health authorities of the American continent. In Brazil, few data are available to evaluate the real situation of endemic areas for CD, mainly in the Northeast region. Thus, the objective of the study was to evaluate the living conditions, clinical aspects and prevalence of infection in inhabitants of rural areas endemic to CD. Blood was collected and submitted to diagnostic ELISA and indirect immunofluorescence techniques. A questionnaire covering sociodemographic information and knowledge related to CD was applied, and general clinical evaluation and swallowing assessment were performed. Twenty-four (7.04%) seropositive individuals were identified, of whom 83.3% were women with most in the age range of 30-60 years old. The majority of the population has a low level of education. Regarding the risk variables for CD, an association was noted between the presence of kissing bugs (OR 9.8) and contact/manipulation (OR 20.2), transfusion (OR 10.6), and sugarcane juice intake (OR 5.1). Was possible to detect changes in swallowing. The present study revealed the existence of a population seropositive for CD without follow-up for their health condition. In addition, some of these patients present changes in swallowing that may be related to the chronic phase. Although no infected children were identified, the area may be considered at risk due to the environmental and socioeconomic conditions of its population and the presence of infected vectors previously found in the area.
