| seroprevalence of trypanosoma cruzi infection among school-age children in the endemic area of guatemala. | in support of the national program for chagas disease control, we conducted a cross-sectional study to estimate the seroprevalence rate of trypanosoma cruzi infection across the five departments (chiquimula, jalapa, zacapa, jutiapa, and santa rosa) that are believed to comprise the entire principal endemic area in guatemala. also, so that the results could be used to identify areas of active transmission, we conducted the survey in school-aged children. we used an experimental enzyme-linked immu ... | 2003 | 12887026 |
