The global burden of disease (GBD) refers to the collective impact of diseases, injuries, and risk factors on global populations, measured through metrics such as disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs). Understanding the GBD is crucial for prioritizing public health interventions, allocating resources efficiently, and formulating policies that address the most significant health challenges worldwide. Health economics plays a pivotal role in this context by providing a framework for analyzing the costs and benefits of health interventions, thus informing decisions that maximize health outcomes relative to available resources. Understanding the Global Burden of Disease Measurement Tools Disability-Adjusted Life Years (DALYs): DALYs are a composite measure that combines YLLs and YLDs. One DALY represents one lost year of "healthy" life. The sum of DALYs across the population gives an estimate of the total disease...
