A cross-sectional study was undertaken in order to determine the seroprevalence of chagasic infection in people living in the urban and rural zones of the town of Guateque, department of Boyacá. Antibodies aginst T. cruzi were detected by enzyme irnmunoassay (ELISA). The prevalence and distribution of infection according to gender, 10-year age groups and rural and urban residence were determined. Adjusted risks of infection were determined by non conditional logistic regression which included the variables already mentioned. Prevalence of infection varied from O to 88 %. In the rural zone the prevalence was 34.5 % while in the urban zone it was 5.3%. The correrelation between age and time of residence in the area, albeit low, was positive in all age groups, except for the 20-29 and 30-39 groups in which it was negative. Interestingly, a protective effect OR=0.6 for infection was found in the male gender.
