19. Some 6 million people worldwide are blind because of trachoma, and more than 150 million people are in need of treatment.

It is the leading cause of preventable blindness. The disease is strongly related to overcrowding and the absence of nearby sources of safe water for washing the face and hands. Improving access to safe water sources and better hygiene practices can reduce trachoma morbidity by 27 percent.

21. Arsenic is naturally present at high levels in the groundwater of a number of countries.

Arsenic is highly toxic in its inorganic form.

Contaminated water used for drinking, food preparation and irrigation of food crops poses the greatest threat to public health from arsenic.

22. Long-term exposure to arsenic from drinking-water and food can cause cancer and skin lesions. It has also been associated with cardiovascular disease and diabetes. In utero and early childhood exposure has been linked to negative impacts on cognitive development and increased deaths in young adults.

27. Researchers have estimated that each year there are 1.3 million to 4.0 million cases of cholera, and 21 000 to 143 000 deaths worldwide due to cholera

To prevent the spread of cholera, the following four interventions are essential:

Provision of adequate safe drinking-water

Proper personal hygiene

Proper food hygiene

Hygienic disposal of human excreta.
