Diarrhoeal diseases claim the lives of around two million children each year- 5,000 per day, and cause countless more to fall ill. Children already suffering from poor diets and the ravages of other diseases are the first to get sick and die from water and sanitation-related diseases such as diarrhoea, cholera and typhoid, UNICEF says. Diarrhoea spreads most readily in environments of poor sanitation where safe water is unavailable – often areas that have been hit by human made or natural disasters. Water-borne diseases are one of the major cases of under-five mortality, along with pneumonia, malaria, and measles.
