This is a C&P from a UNICEF 2013 document showing some, to me, shocking and indeed sickening figures of the percentage of babies/children affected.
"The countries where it is concentrated and the percentage of women affected:
Somalia (98 percent), Guinea (96 percent), Djibouti (93 percent), Egypt (91 percent), Eritrea (89 percent), Mali (89 percent), Sierra Leone (88 percent), Sudan (88 percent), Gambia (76 percent), Burkina Faso (76 percent), Ethiopia (74 percent), Mauritania (69 percent), Liberia (66 percent), Guinea-Bissau (50 percent), Chad (44 percent), Côte d'Ivoire (38 percent), Kenya (27 percent), Nigeria (27 percent), Senegal (26 percent), Central African Republic (24 percent), Yemen (23 percent), United Republic of Tanzania (15 percent), Benin (13 percent), Iraq (8 percent), Ghana (4 percent), Togo (4 percent), Niger (2 percent), Cameroon (1 percent), and Uganda (1 percent).
It also seems to be supported by some Coptic Christians in Sudan.
