摘要
目的研究三峡成库后三峡库区湖北段生态环境和社会经济变化对血吸虫病流行的影响,为制订防治方案提供科学依据。方法采取流行病学方法对三峡库区湖北段血吸虫病传染源输入和中间宿主钉螺输入、孳生等可能危险因素进行研究,并提出相应的预防对策和建议。结果建坝后库区湖北段生态环境改变,对钉螺的孳生十分有利,钉螺和传染源输入库区可能形成新的流行区。结论三峡成库后,库区湖北段生态环境发生变化,存在血吸虫病流行的潜在性危险。
Objective To study the impact of the ecological changes and the development of the society and economy in the Three Gorges Reservoir areas in Hubei on the prevalence of schistosomiasis and to provide a scientific basis for preventing schistosomiasis. Methods Such risk factors of schistosomiasis transmission in Hubei were analyzed, as the probability of inputing, the source of the infection and propagation of Oncomelania, using epidemiological methods. Relative prevention strategies and suggestion were proposed in this paper. Results Data showed that Oncomelania could survive and reproduce in the changing environment of Hubei, once Oncomelania and the infectious resources of schistosomiasis were introduced into the Three Gorges Reservoir areas in Hubei, the area would become a new schistosomiasis epidemic area. Conclusion The potential danger of schistosomiasis prevalence exists in Hubei when the ecological environment has been changed after the construction of the Three Gorges Reservoir areas.
