山东省控制华支睾吸虫病的研究

目的调查华支睾吸虫病流行范围,流行规律和危害程度,探索华支睾吸虫病的诊断与防治方法,采取有效的防治技术措施,降低人群感染率及其危害,达到阻断传播控制流行。方法使用回顾性研究方法,对全省40年来有关华支睾吸虫病的调查、研究、防治资料等进行统计分析研究。结果山东省1962年发现华支睾吸虫病,全省132个县（市、区）中的107个有不同程度的流行,人群感染率为1.51%,村感染率为1%～30%,个别学校高达40%以上,85.7%的感染者为15岁以下少年儿童。经过几十年的综合防治,至上世纪90年代人群感染率降至0.3%,91.6%的流行村感染率降至1%以下,以县为单位统计40%的原流行县未检出感染者,2002年重点县区人群感染率降至0.04%。结论山东省已成功控制华支睾吸虫病流行。传染源查治与健康教育相结合是主要的控制措施。

Study on the control of clonorchiasis sinensis in Shandong Province, China

Objective To survey the epidemic scopes,epidemic rules and the degrees of damage of clonorchiasis,to search for the methods of diagnosis and control of clonorchiasis,and to take the effective control measures and reduce the infection rate of population as well as its damage in order to obtain the aims of blocking the transmission and controlling prevalence.Methods The data of the investigation,research and control of clonorchiasis in Shandong Province during the past forty years were collected and analyzed.Results The clonorchiasis in Shandong Province was found in 1962,and prevailed among 107 counties in 132 of whole province were confirmed by investigation.The infection rates of population and villages were 1.51%,and 1%-30%,respectively,the infection rate of some schools was more than 40%,85.7% of the infected people were children below fifteen years old.Through forty years' control,the population infection rate dropped to 0.3%,the infection rate of 91.6% epidemic villages dropped to less than 1%.The infected people were not found in 40% of former epidemic counties according to the analysis of counties acted as an unit.The infection rate of the main counties dropped to 0.04%.Conclusion The clonorchiasis in Shandong Province has been controlled successfully,combination of examination and treatment of infectious source and healthy education is the main control measure.
