International charities warned that, left unchecked, the disease’s spread might exacerbate similar outbreaks across the African region for weeks or months to come.

Cholera has spread in Sudan. The medical charity MSF says it's the worst outbreak of its kind in many years in a country already gripped by armed conflict.

An aid group says cholera is spreading rapidly in Darfur. Doctors Without Borders says that the outbreak has killed 40 people and infected more than 2,300 in the past week.
