The Global Burden of Disease (GBD) is a comprehensive study that measures the impact of diseases, injuries, and risk factors on populations worldwide. It evaluates health outcomes by considering factors like mortality, disability, and quality of life. This information helps policymakers and health organizations prioritize health interventions and allocate resources effectively. GBD data is collected from various sources, including hospitals, surveys, and health records, to provide a detailed picture of health trends across different regions and demographics. By understanding the burden of diseases, countries can implement targeted strategies to improve public health and reduce health disparities.
