title: Prevalence of Chagas' disease in Mulungu do Morro northeastern Brazil.
abstract: OBJECTIVE
  The aim of this paper is to describe the prevalence of T. Cruzi infection in patients of from Mulungu do Morro, a rural tropical region of Northeastern Brazil.
  
  
  METHODS
  A cross-sectional study was performed. After randomly selecting samples of the population, and obtaining their consents, patients completed pretested epidemiological and clinical questionnaires. Serum samples from all patients were collected and screened for the presence of T. cruzi antibodies.
  
  
  RESULTS
  Of 694 patients examined, 174 patients (25.1%) tested had a positive serology for Chagas' disease. Of the study population, 341 patients were male with 27% Chagas' disease prevalence, without a statistical difference. Illiteracy was the only variable related to T. cruzi infection in our population.
  
  
  CONCLUSIONS
  In conclusion, our study points to the high prevalence of Chagas' disease among patients in Mulungu do Morro, suggesting that this region has a high frequency of infection and probably active vectorial transmission.
