目的研究西昌市邛海湿地生态建设对当地血吸虫病流行的影响,为制定相关防治对策提供科学依据。方法对邛海湿地生态建设的过程及方法回溯调查,并对邛海湿地建设涉及的11个血吸虫病流行村开展人群血吸虫感染情况和钉螺监测,了解湿地建设前后生态环境变化对螺情和病情的影响。结果邛海湿地建设前,对周边环境进行了灭螺,并对常住居民以吡喹酮进行扩大化疗,建成后的湿地道路、沟渠硬化。人群血吸虫感染率从2009年的0.37%下降到2014年的0。螺情监测未发现血吸虫感染性钉螺,近2年未发现钉螺,哨鼠传播风险监测,未发现血吸虫感染性小鼠。结论邛海湿地建设有效消灭了湿地内原有的钉螺,在一定程度上阻断了血吸虫病的传播。但是建成后的湿地环境更适宜钉螺孳生和扩散,因此仍需加强监测。
Objective To study the impact of the ecological construction of Qionghai wetland in Xichang on the prevalence of schistosomiasis in the local area and provide a scientific basis for making relevant control strategies. Methods The retrospective investigation was made on the process and methods of ecological construction in the Bahai Lake wetland. The infection status of schistosomiasis and snail monitoring in 11 schistosomiasis-endemic villages involved in the construction of the Bahai wetland were investigated. The changes of ecological environment before and after wetland construction were analyzed. influences. Results Before the construction of Qionghai wetland, molluscicide was applied to the surrounding environment, and extended treatment was carried out on the resident population with praziquantel. After the completion of the wetland road, ditches were hardened. The prevalence of human schistosomiasis has dropped from 0.37% in 2009 to 0 in 2014. Snail infection was not found in snails infection of schistosomiasis, snail found in the past two years, the risk of transmission of sentinel rats did not find schistosome infective mice. Conclusion The construction of the Huanghai wetland effectively eliminated the original snail in the wetland and blocked the transmission of schistosomiasis to a certain extent. However, after the completion of the wetland environment is more suitable for snail breeding and proliferation, it is still necessary to strengthen monitoring.
