Finding appropriate ways of dealing with the problem of tsetse and trypanosomosis will be an important component of efforts to alleviate poverty in Africa. This article reviews the history of economic analyses of the problem, starting with the use of cost to guide choice of technique for tsetse control in the 1950s, followed by work in the 1970s and 1980s linking these to the impact of the disease on livestock productivity, and in the 1990s to its wider impact. In the current situation, with limited resources and a range of techniques for controlling or eliminating tsetse, the cost implications of choosing one technique or another are important and a recent study reviewed these costs. A novel approach to assessing the potential benefits from removing trypanosomosis by creating 'money maps' showed that high losses from animal trypanosomosis currently occur in areas with high cattle population densities on the margins of the tsetse distribution and where animal traction is an important component of farming systems. Given the importance of the decisions to be made in the next decade, when prioritising and choosing techniques for dealing with tsetse and trypanosomosis, more work needs to be done underpinning such mapping exercises and estimating the true cost and likely impact of planned interventions.
找到处理采采蝇和锥虫病问题的恰当方法，将是减轻非洲贫困努力的一个重要组成部分。本文回顾了对该问题进行经济分析的历史，从 20 世纪 50 年代利用成本指导采采蝇控制技术选择开始，接着是 70 年代和 80 年代将这些与疾病对牲畜生产力的影响联系起来的工作，以及 90 年代将其与更广泛的影响联系起来的工作。在当前资源有限且有多种控制或消除采采蝇的技术的情况下，选择一种技术而不是另一种技术的成本影响是重要的，最近的一项研究对这些成本进行了审查。通过创建“货币地图”来评估消除锥虫病的潜在收益的新方法表明，目前动物锥虫病的高损失发生在采采蝇分布边缘的高牛群密度地区，以及动物牵引力是农业系统的重要组成部分的地区。鉴于在未来十年做出决策的重要性，在确定优先事项和选择处理采采蝇和锥虫病的技术时，需要做更多的工作来支持这种映射工作，并估算计划干预措施的真实成本和可能影响。
