  1. The categories for the intensity of S. haematobium infection were defined according to WHO guidelines as: none: 0 e/10 ml; light: < 50 e/10 ml and heavy: ≥ 50 e 10 ml.
  2. The categories for the intensity of S. mansoni infection were defined according to WHO guidelines as: none: 0 epg; light: 1-99 epg; moderate: 100-399 epg; and heavy: ≥ 400 epg
  3. e/10 ml, eggs/10 milliliters & epg, eggs per gram
  4. These categorizations for both schistosomes species apply for all tables presented beyond this point.
