Cholera has swept through Yemen faster than any other country on record this year.
The cholera epidemic in Yemen is a 'man-made crisis' because of three years of war, says Nigel Timmins, Humanitarian Director of the aid agency Oxfam. (Photo: A Yemeni child suspected of being infected with cholera receives treatment at a hospital in Sanaa. Credit: AFP/Getty Images)
Sabaen Hospital in Yemen's capital, Sanaa, is treating hundreds of patients infected with cholera.
Yemen is now facing the world's worst cholera outbreak. With clean drinking water in short supply, the water-borne disease has rapidly spread across Yemen. The UN says the number of suspected cholera cases in the country has just exceeded 220,000.
