- •
77% of 410 school children were PCR-positive for Schistosoma sp.
- •
Stool sedimentation microscopy was positive for Schistosoma mansoni eggs in 15%.
- •
Sensitivity and specificity estimates for stool sedimentation microscopy: 19.3%, 98.5%.
- •
Sensitivity and specificity estimates for PCR: 95.3%, 94.9%.
- •
The Bayesian posterior estimate of the prevalence is 80.2%.
