Schistosomiasis was severely prevalent in Yunnan Province, and it is difficult to achieve its elimination by convention approaches due to complexity of the nature. We explored the comprehensive model to eliminate schistosomiasis in Eryuan County, Yunnan Province, the People's Republic of China, through integration with the ecological protection programme in Erhai Lake, in order to promote an efficient elimination strategy. We expected that this model is able to be tailored to other local settings, which help achieve the goal of precisely eliminating the disease in Yunnan Province.
Eryuan County of Yunnan Province was chosen as the study area, where the data on environmental protection activities in Erhai Lake and on the schistosomiasis control programme were collected through different departments of Erhai County government since 2015. System modelling was performed using system dynamics software to establish a simulation model in order to evaluate the effectiveness of intervention activities.
Ecological approaches to control schistosomiasis in Eryuan County consist of three major components: (i) implementing precise interventions to stop schistosomiasis transmission by means of controlling the source of infection, blocking the biological transmission chains and cutting off the route of disease transmission; (ii) employing ecological approaches to improve the co-effectiveness of environmental protection and schistosomiasis prevention in the study area; and (iii) strengthening the professional skills of personnel involving in the schistosomiasis control programme. Simulation results showed that this strategy could speed up the progress of schistosomiasis control programme moving from the control stage to the elimination stage.
Ecological approaches implemented in schistosomiasis endemic areas of the Eryuan region are able to improve the co-effectiveness of environmental protection and schistosomiasis control, providing a new avenue for eliminating schistosomiasis thanks to the application of precise interventions.
云南省曾是血吸虫病重疫区，由于自然因素的复杂性，常规方法难以实现消除目标。本研究旨在探索将洱海生态保护项目与云南省洱源县血吸虫病防治工作相融合的综合防治模式，以推动高效的消除策略，为其他地区提供可借鉴的经验，助力云南省精准消除血吸虫病。
选择云南省洱源县作为研究现场，收集 2015 年以来洱源县政府各部门关于洱海生态保护活动和血吸虫病防治工作的数据，采用系统动力学软件建立模拟模型，对干预措施的效果进行评价。
洱源县血吸虫病生态防治策略主要包括三个部分：（i）实施精准干预，通过控制传染源、阻断传播途径和消灭钉螺，阻断血吸虫病传播；（ii）采用生态措施提高研究区环境保护与血吸虫病防治的协同效应；（iii）加强血吸虫病防治专业人员的技能。模拟结果表明，该策略可以加快血吸虫病防治工作从控制阶段向消除阶段的推进。
在洱源县血吸虫病流行地区实施生态措施，能够提高环境保护和血吸虫病防治的协同效应，通过精准干预为消除血吸虫病提供了新途径。
