Global Burden of Disease: Determining Priorities on a Global Scale

The Global Burden of Disease is the most comprehensive effort to measure epidemiological levels and trends worldwide using big data, disease models, and a network of disease and country experts. In the GBD, we estimate disease prevalence and quantify the relative harm caused by 300 diseases and injuries. Disability-adjusted life years allow comparison of diseases and different health outcomes. GBD data are used to set global priorities and to understand how health challenges are shifting over time.
