Cost-effectiveness

Estimates are sourced in their native units and shown for comparison, not as literal costs. Sources use different frameworks — see each card for what it represents and how it was derived.

WHO-CHOICE estimates are modeled at 50% population coverage, compared against the null set (no intervention) under generalized cost-effectiveness analysis. View WHO-CHOICE methodology →

$/DALY sources differ by 2.8x - a material difference.

Modeled regional estimates — not realized delivery costs.
