Burden of disease

The burden of disease is a measurement of the gap between a population’s current health and the optimal state where all people attain full life expectancy without suffering major ill-health.
Burden of disease analysis enables decision makers to identify the most serious health problems facing a population.
Loss of health in populations is measured in disability-adjusted life years (DALYs), which is the sum of years of life lost due to premature death and years lived with disability.
