CHE1: catastrophic health expenditure measured by annual out-of-pocket payments exceeding 40% of the household’s annual capacity to pay during TB treatment

CHE2: catastrophic health expenditure measured by annual out-of-pocket payments exceeding 10% of the household’s annual income during TB treatment
