Of particular importance is water polluted with fecal matter through wastewater, septic tanks, and latrines, for instance. Microbes that can induce diarrhea are often present in animal feces.
Other causes: Diarrhoeal infection, compounded by inadequate basic grooming, also can spread through the air. Food is yet another significant cause of disease when cooked or handled in unsanitary conditions. The preparation and treatment of contaminated mains sewage is also a significant risk factor. Smoggy fish and shrimp can also lead to the infection.
