Years of life lost (YLLs)
This is a measure of fatal health loss. It takes into account the number of deaths and the age at death.
Disability-adjusted life years (DALYs)
A DALY is an integrated measure of health loss. It is the sum of years of life lost (YLLs) and years lived with disability adjusted for severity (YLDs). One DALY represents the loss of one year of life lived in full health.
