Sudan has been stricken by a cholera outbreak that has killed nearly two dozen people and sickened hundreds more in recent weeks, health authorities said Sunday. The African nation has been roiled by a 16-month conflict and devastating floods.

Health Minister Haitham Mohamed Ibrahim said in a statement that at least 22 people have died from the disease, and that at least 354 confirmed cases of cholera have been detected across the county in recent weeks.
