Abstract
Background
We screened for Trypanosoma cruzi infection amongst children in a rural community in the Bolivian Chaco, an area known for high prevalence. We also estimated the force of infection (FOI).
Methods
423 children were screened using InBios (Seattle, WA) ChagasDetectPlus (CDP) rapid test at the local school. CDP-positive specimens were further tested by indirect hemagglutination assay (IHA) and Wiener Recombinante v3.0 ELISA. A catalytic model was used to estimate FOI.
Results
Confirmed seroprevalence was 0.22, rising steeply with age. The mean age of seropositive individuals was 13 years. Rapid test specificity was calculated 91.9%, the annual incidence estimated from the FOI was 0.021.
Conclusion
This study demonstrates persistent transmission and continued high levels of T. cruzi infection in the Bolivian Chaco, and highlights the practicality of school-based screening
