Seroprevalencia de infección por trypanosoma cruzi en población urbana y rural de guateque (colombia)

Se realizó un estudio de corte transversal para determinar la seroprevalencia de la infección chagásica en personas que viven en zona urbana y rural de Guateque (Boyacá). Se detectaron anticuerpos contra Trypanosoma cruzi mediante la técnica de ELISA. Se determinó la prevalencia de infección por género, grupos etáreos decenales y ubicación urbana y rural. Se calcularon los riesgos ajustados de infección mediante regresión logística no condicional incluyendo las variables mencionadas. Las prevalencias de infección variaron entre O y el 88% siendo en la zona rural del 34.5% y en la urbana del 5.3%. La prevalencia de infección por grupos etáreos no se comportó como en otros estudios. La correlación entre edad y tiempo vivido en la zona por grupo etáreo es baja pero positiva en todos los grupos de edad excepto en los de 20-29 y 30- 39, en los que fue negativa. Como hallazgo interesante se encontró un OR de 0.6 para el género masculino.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
