The humanitarian organization described this as the worst cholera outbreak Sudan has seen in years. The situation is especially dire in Darfur region.

At least 40 people have died from cholera in Sudan’s Darfur region in what medical charity Doctors Without Borders, known by its French initials MSF, described as the country’s worst outbreak in years.

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