Microscopy overestimated E. histolytica prevalence by 23% compared with PCR, due to non-pathogenic species. Four E. histolytica infections and one Cryptosporidium infection were PCR-confirmed. Ct values correlated with microscopy intensity (p&amp;lt;0.01), but detection was not linked to symptoms. The only cohort difference was water source: 48% in Cohort 2 vs 23% in Cohort 1 had private water posts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Children in Bissau carry a high asymptomatic burden of G. duodenalis.
