Open defecation is the practice of defecation without any kind of sanitation system and is generally accepted to lead to health problems such as cholera, dysentery, diarrhoea, jaundice, typhoid, polio and intestinal worms, either by contamination of clean water supplies or by direct handling of excrement.
Globally, more than a billion people (15% of the total population) practice open defecation.[1]
Appropriate technology sanitation systems aim to improve health outcomes by providing interventions that move human excrement away from the household, out of reach of children and to treat it before release into the environment.

Literature review and discussion[edit | edit source]
There is good evidence to suggest that almost all forms of sanitation are better than open defecation. A 2010 review paper[2] systematically considered 15 high quality research papers comparing open defecation to various forms of improved sanitation. It found that 13 of the 15 studies showed an improvement in diarrhoeal incidence, and some gave very large reductions.
Stenström[3] et al conducted a risk assessment of many common components used in WASH systems. They concluded that open defecation represents a high risk of daily infection for users and a high risk of infection to the general community who have to live with it.
