Cost savings resulting from confirmatory mapping in Ethiopia and Tanzania, calculated by comparing the costs of the mapping surveys with the averted costs for districts that passed and did not required MDA treatment.埃塞俄比亚与坦桑尼亚两国开展确认性绘图（confirmatory mapping）所产生的成本节约额，通过对比绘图调查的成本与达标且无需大规模药物投放（MDA，Mass Drug Administration）治疗的地区所避免的成本计算得到。
