Evidence suggests that the safe disposal of child feces may be effective in preventing diarrhea. However, the evidence is limited and of low certainty. The limited research on STH infections provides only low and very‐low certainty evidence around effects, which means there is currently no reliable evidence that interventions to improve safe disposal of child faeces are effective in preventing such STH infections.
While child feces may represent a source of exposure to young children, interventions generally only address it as part of a broader sanitation initiative. There is a need for RCTs and other rigorous studies to assess the effectiveness and sustainability of different hardware and software interventions to improve the safe disposal of feces of children of different age groups.
