Chronic diseases, such as heart disease, stroke, cancer, chronic respiratory diseases and diabetes, are by far the leading cause of mortality worldwide, representing 60% of all deaths. Contrary to common perception, 80% of chronic disease deaths occur in low- and middle-income countries. This invisible epidemic is an underestimated cause of poverty and hinders the economic development of many countries. Sub-Saharan Africa carries the highest burden of disease in the world, the bulk of which still consists of the communicable diseases HIV/AIDS, tuberculosis and malaria.
