Yemen's civil-war cholera outbreak (2016–2018)
Cholera swept through Yemen during the civil war, becoming the world's largest outbreak in modern history with over a million suspected cases in the peak year. Bombing and neglect destroyed water and sewage systems.
Hospitals overflowed and treatment centres became a daily fixture across the country.
The outbreak became the reference case for how conflict fuels waterborne disease.
It parallels Sudan: war-damaged infrastructure and restricted access are the drivers, and vaccination plus clean water are the only reliable levers.
