Chad Buckles Under Sudan's Spillover as Cholera and Meningitis Spread

Chad is bearing an immense and growing weight from the war raging next door in Sudan, having registered more than 888,000 refugees and 330,000 returnees fleeing the conflict — a humanitarian burden that is now colliding with a public-health emergency of its own.

A cholera outbreak first declared in mid-2025 has worsened rather than eased, and meningitis cases are surging through the overcrowded refugee camps in eastern Chad that house hundreds of thousands of people who fled the fighting across the border. Disease spreads fastest where sanitation is weakest and populations are densest, and Chad's camps offer both conditions in abundance.

The crisis extends beyond the refugee influx. The Lake Chad Basin, long one of the most fragile regions in the Sahel, is described by analysts as entering a renewed phase of deterioration after a period of fragile stabilisation — a reminder that Chad's troubles are compounding rather than resolving. Jihadist violence, climate pressures and now a refugee emergency are converging on a country with limited resources to absorb any one of them alone, let alone all three.

International humanitarian agencies have mobilised, but the scale of need dwarfs the funding and capacity available. Camps built for smaller populations are stretched far beyond their intended limits, water and sanitation systems are overwhelmed, and health workers are contending with outbreaks in conditions that make containment extraordinarily difficult.

Chad's predicament illustrates a broader pattern across the region: wars in one country rarely stay contained within its borders, and the neighbours least equipped to cope often bear the heaviest cost. For the refugees and host communities alike, the emergency shows no sign of easing.
