CKDu or chronic kidney disease of unknown etiology/uncertain cause is a type of chronic kidney disease that mainly affects marginalized agricultural communities in specific areas of the world where a large number of people develop an unexplained, deadly form of kidney disease.
Because the populations affected are some of the world’s poorest and are exposed to a high degree of occupational and environmental hazards, and because the disease is considered a ‘medical mystery,’ CKDu has received significant attention in scientific magazines and the media.
