摘要
目的追踪观察广东省阳山县大莨村防治华支睾吸虫病的远期效果,探讨防治策略,为制订防治华支睾吸虫病的技术措施提供科学依据.方法防治前调查大莨村华支睾吸虫的感染情况,观察指标包括人群、中间宿主及保虫宿主的感染率等,其中人群感染率通过粪检普查确定;防治措施包括药物治疗华支睾吸虫带虫者、环境治理和卫生宣教等;防治后进行30年不定期的追踪观察.结果防治前(1975年)大莨村人群、长角涵螺及淡水鱼虾的华支睾吸虫感染率分别为48.25%(69/143)、27.52%(30/109)、20.00%～33.33%;受检家犬感染率为91.67%(11/12).防治措施实施6个月后人群感染率下降至2.90%;1979～1982年间共3次普查人群感染率均为0;1985年再次调查发现2例感染者,感染率为1.26%;2004年抽查1/2人群,感染率为1.09%(1/92),检出的唯一感染者为输入性感染;2005年复查全村村民共183人,未发现感染者.1979年及1982年对中间宿主、保虫宿主复查,仅在麦穗鱼中发现华支睾吸虫,两次感染率分别为50%(10/20)、22.45%(22/98),2005年共检查麦穗鱼、长角涵螺、家犬等样本513份均为阴性.结论大莨村实施的华支睾吸虫病综合防治措施效果显著.彻底查治传染源结合环境治理及卫生宣教的策略,可有效地控制华支睾吸虫病流行,而且远期效果巩固,值得推广应用.
Objective To evaluate the long-term effect of clonorchiasis control program in Dalang village. Methods The observation indexes included the infection rates of the resident, intermediate host and reservoir host etc. Infection rate was determined by stool examination. The control measures included hexaehloroparaxylene treatmaent, environment management and health promotion and the program was carried out for 30 years. Results Before the program started （1975）, the infection rates of the resident and intermediate hosts were 48.25% and 20.00% - 33.33% respectively. The infection rate of dogs was 91.67%. The resident infection rate decreased to 2.90% after six months, 0 between 1979 - 1982, 1.26% in 1985, 1.09% in 2004 and 0 in 2005. The infection rates of intermediate host were 50%, 22.45% and 0 in 1979, 1982 and 2005 respectively. Conclusion The results showed that the comprehensive control program was effective.
