Schistosomiasis infections are associated with water contact and open defecation.
Is it true that schistosomiasis infections are associated with water contact and open defecation?
Yes. Multiple epidemiological studies and reviews confirm that schistosomiasis transmission is strongly driven by freshwater contact activities and inadequate sanitation practices such as open defecation.
Verdict: SUPPORTED · 10 sources for, 0 against · Last checked
The retrieved literature extensively documents that schistosomiasis is a water-borne/water-based disease linked directly to freshwater contact (such as swimming, bathing, fishing, and domestic use) and poor sanitation/hygiene practices, including defecating or urinating in water bodies. All relevant papers support this established epidemiological consensus, and none refute it.
