War-torn Sudan is in the grips of one of its worst cholera outbreaks in years. More than 100,000 people have been infected by the disease and over 2,400 lives lost since the outbreak was declared last year. The war has been fuelling the crisis, forcing mass displacement and as people move, so does the disease. Cholera has now crossed into neighbouring Chad, where thousands have sought refuge. In the east of the country, at least 68 deaths have been reported in just one month. Aid agencies are warning that if urgent action isn't taken, the region could be pushed to the brink of a wider epidemic. One of those NGOs is Solidarités International. Its executive director Kevin Goldberg spoke to us in Perspective.
