DALYs

Disability-Adjusted Life Years (DALYs) is a metric used to measure the overall burden of disease in a population. It combines years of life lost due to premature mortality (YLLs) and years lived with disability (YLDs) into a single measure. DALYs are calculated by adding the YLLs to the YLDs for a given disease or condition. The DALY is expressed as a number of years, with one DALY representing one year of healthy life lost.

YLLs are calculated by multiplying the number of deaths by the average age of death, which is

DALYs are used to compare the burden of different diseases and to evaluate the effectiveness of interventions.

The DALY is a valuable tool for understanding the impact of diseases on populations, but it has
