A pоlicymаker is cоmpаring the heаlth burden оf tuberculosis between Country A and Country B. Both countries report similar numbers of TB deaths per year.

The policymaker wants a single metric that captures both the deaths and the ongoing disability burden so she can make a fair comparison between the two countries. Which metric should she use?
