Cholera cases in war-torn Sudan increased by nearly 40% in less than two weeks, according to the latest figures, alarming the U.N. health officials, who long warned about the outbreak and the lack of proper response since it was reported in July.

The marked increase in cholera and dengue cases is part of a broader health crisis in Sudan, where fighting between the army and paramilitary Rapid Support Forces has raged since April 2023. Other epidemic diseases, including malaria and measles, have also spread.

Sudan’s cholera outbreak continues to escalate, with the Ministry of Health reporting on Thursday that cases have surpassed 19,000, including 566 fatalities. The outbreak began on August 12, following widespread flooding across Sudan.
