Objective: To determine the prevalence of antibodies against Trypanosoma cruzi in pregnant women in endemic areas of Boyacá, Colombia, in 2012 and 2013.
Materials and methods: Cross-sectional study of 566 pregnant women from endemic municipalities of Boyacá. Samples were analyzed by means of serological tests for Chagas, namely: IgG ELISA, indirect immunofluorescence and indirect hemagglutination. Cases with positive results in two tests were considered as confirmed.
Results: The overall prevalence of antibodies against Trypanosoma cruzi was 2.5 % (14/566). Municipalities with the highest prevalence were Chitaraque (8.3 %), and Soatá (3.3 %). Average age of positive women was 32.6 years, and their gestational period, 18.1 weeks. We found a statistically significant association between age and the presence of antibodies against Trypanosoma cruzi.
Conclusion: Prevalence of antibodies against T. cruzi in pregnant women demonstrates the importance of the monitoring program for Chagas disease in pregnancy, as a method for congenital disease control.
