Updating the DALYs for diarrhoeal disease.

Estimates of global disease burden remain high on the international research and policy agenda as a forum for ranking health priorities. Within this, the quality of life or years lived with varying degrees of disability has been recognized as an important outcome that should be considered alongside estimates of mortality. Recent studies into the long-term consequences of diarrhoeal diseases on physical and mental development suggest that the disability adjusted life year calculations for these conditions could require updating.
