Faecal-oral transmission refers to the process whereby disease is transmitted via the faeces of an infected individual, to the mouth of a susceptible individual. This transmission can occur through failures in sanitation systems along the sanitation chain (toilet, containment, conveyance, treatment, end use, and disposal) leading to exposure via various routes including food, water, hands, flies, inanimate objects or surfaces, as illustrated below:

Faecal-oral transmission can be interrupted by water, sanitation, and hygiene (WASH) interventions.
