1 in 3 women have no access to clean facilities

About 2.4 billion people around the world don't have access to decent sanitation, and more than 1 billion are forced to defecate in the open, risking disease and other dangers, according to the United Nations.

Launching its World Toilet Day campaign for Thursday, the UN said poor sanitation increases the risk of illness and malnutrition, especially for children, and called for women and girls in particular to be offered safe, clean facilities.
