Assumed per-patient cost (US $) of projected TB interventions by country group.

Notes: Stated amounts reflect unit costs in US$ as of 2010, of (i) diagnosing and treating one TB patient under DOTS [1] and (ii) the additional cost incurred if the patient has multi-drug resistant (MDR) TB as estimated in the WHO/Stop TB partnership Global Plan to Stop TB 2011–2015 [1], and (iii) the additional cost incurred if the patient is HIV-positive and receives antiretroviral therapy (ART) for the duration of a 6-month DOTS course [47]. Costs are inflated at 3% per annum. Regional cost estimates were based on country cost estimates, weighted by each country’s notified incident cases.
