Laura H. Kwong e outros, 2021 · PLoS Neglected Tropical Diseases
Providing dual-pit latrines, child potties, and feces management tools did not significantly reduce the prevalence of soil-transmitted helminth eggs in household courtyard soil.

The sanitation intervention had no significant impact on the prevalence in soil of total A. lumbricoides eggs (PR = 0.97 (95% CI: 0.88–1.06)), T. trichiura eggs (PR = 1.03 (95% CI: 0.92, 1.15)), any STH eggs (PR = 0.98 (95% CI: 0.91, 1.05)
Contexto
What changed: Households received improved dual-pit latrines, potties, sani-scoops, and regular hygiene promotion visits. Comparison: Control households receiving no intervention. Limits: While adult latrine use was high, open defecation by young children and unhygienic child and animal feces disposal remained widespread.
