GOMA, DRC OCTOBER 4: Unidentified women stand in a hospital ward with their children on October 4, 2006 in central Goma, DRC. The hospital is run by Heal Africa, an NGO. These women are suffering from Goiter, the enlargement of the thyroid gland, due to the shortage of Iodine in food. Most people in DRC eat cassava, which is not high in Iodine. Due to the recent civil war, Congo has the worst humanitarian crisis since World War 2. About four million people have died of treatable diseases. Many women has been abducted and used as sex slaves by different militias and rebel groups during the conflict..(Photo by Per-Anders Pettersson/Getty Images)..
