$${\text{YLD}} = {\text{Number}}\,{\text{of}}\,{\text{cases}} \times {\text{duration}}\,{\text{till}}\,{\text{remission}}\,{\text{or}}\,{\text{death}} \times {\text{disability}}\,{\text{weight}}$$
(1)
$${\text{YLL}} = {\text{Number}}\,{\text{of}}\,{\text{deaths}} \times {\text{life}}\,{\text{expectancy}}\,{\text{at}}\,{\text{the}}\,{\text{age}}\,{\text{of}}\,{\text{death}}$$
(2)
$${\text{DALY}} = {\text{YLD}} + {\text{YLL}}$$
