CKDnT: a fatal epidemic driven by occupational factors

Chronic Kidney Disease of undetermined causes (CKDnT) is a fatal progressive loss of kidney function that has killed more than 20,000 people in a single decade in Central America alone 1 with over 20,000 more dead in Sri Lanka 2, and uncounted more in other regions.

Currently, La Isla Network is working to understand the scale and scope of the disease in other impacted regions via the DEGREE initiative, improving access to care with colleagues at PASE and working on effective and scalable workplace interventions with the WE Program.
