以边际效益视角审视中国消除血吸虫病的优化路径

经过70多年的有效防治，我国血吸虫病防治工作已取得举世瞩目的成绩。当前，我国血吸虫病防治进入消除阶段，主要任务是充分利用已有资源强化血吸虫病监测响应、持续巩固已取得的防治成果、防止疫情反弹。因此，如何进一步优化消除血吸虫病干预措施亟待研究。本文在分析我国血吸虫病防治不同阶段社会经济学特征的基础上，结合边际效益基本原理讨论不同阶段干预措施评价需求与优化策略间的关系，提出了如何利用边际效益原理优化防控方案，使血吸虫病防治成本发挥出最大边际效益，为我国最终消除血吸虫病提供最优战略路径。

Optimized pathway to schistosomiasis elimination in China: a scrutiny using a marginal benefit approach

Following concerted efforts for over 7 decades, great achievements have been gained in the national schistosomiasis control program of China. Currently, China is moving towards the stage of schistosomiasis elimination, when the major task is to make full use of available resources to improve schistosomiasis surveillance and response to sustainably consolidate gained schistosomiasis control achievements and prevent re?emerging schistosomiasis. There is therefore an urgent need for optimization of interventions for schistosomiasis elimination. Based on analysis of socioeconomic features at different stages of the national schistosomiasis control program in China, this review discusses the relationship between the needs of assessment of schistosomiasis elimination interventions and the optimized strategy of schistosomiasis elimination at different stages of the national schistosomiasis control program using a marginal benefit approach and proposes the optimized schistosomiasis elimination strategy that allows the highest marginal benefit with currently available schistosomiasis elimination costs, so as to provide the optimal strategic pathway to schistosomiasis elimination and facilitate the achievement of the targets set in Healthy China 2030.
