Abstract: Objective To understand the current prevalence of clonorchiasis in Jiangxi Province. Methods A survey was performed according to the scheme of the 3rd Principal Human Parasites of Jiangxi Province. Based on the ecological regions， a stratified cluster sampling method was applied by the economic and geographic situation. In rural areas， the investigation of C. sinensis was carried out together with the soil?transmitted helminths investigation， and in the urban areas， the random cluster sampling method was applied for the C. sinensis investigation. There were 92 survey sites from 32 counties. The eggs of C. sinensis in stool were examined by Kato?Katz technique， and health knowledge was also investigated by questionnaires in some people at the same time. Results A total of 23 606 sample residents were investigated， and 138 were found infected with C. sinensis， with the infection rate of 0.58%. Light infection was found in most of them. Totally 124 C. sinensis infected persons focused in Xinfeng County， and only a few of infected people scattered in the other counties. In Xinfeng County， 851 residents were investigated. Among them， the infected people were found in all the age groups except the 0? year age group. The highest infection rate appeared in the 70? years group （24.00%）. The male infection rate was 20.29%， which was higher than that of the female （6.25%）， showing a statistically significant difference （P＜0.01）. The infection rate was highest in the population who received high school or technical secondary school education （31.48%）. For the occupation distribution， the infection rate was highest in public officers （39.39%）. The questionnaire survey showed that the infection rate in the populations in Xinfeng County who had the history of eating raw fish or raw shrimp was 33.15%. Conclusions The distribution of C. sinensis infection presents a regional aggregation in Xinfeng County， but in other areas， the distribution is sporadic. It is necessary to continue to carry out the parasitic disease screening， and in Xinfeng County， it is necessary to strengthen the comprehensive prevention and control intervention.

摘要： 目的 了解江西省华支睾吸虫病流行现状和态势。方法 按照江西省第3次人体重点寄生虫感染现状调查方案，以生态区为基础，按照经济条件和地理方位进行分层整群抽样，农村地区华支睾吸虫调查与土源性线虫调查一并进行，城镇地区以随机整群抽样法进行调查。共抽取全省32个县92个调查点进行调查，用改良加藤厚涂片法粪检虫卵并计数，抽取部分人群进行健康知识问卷。结果 全省共调查23 606人，华支睾吸虫感染者138人，感染率为0.58%，以轻度感染为主，感染者主要集中于信丰县，共124人，其余各地有散在感染者。信丰县调查的851人中，除0 ～岁组无感染者外，其余各年龄组均有感染者，70 ～岁组感染率最高（24.00%）；男性感染率（20.29%）高于女性感染率（6.25%），差异有统计学意义（P < 0.01）；文化程度分布以高中、中专学历人群感染率最高（31.48%）；职业分布以干部等公职人员最高（39.39%）；感染途径中，有生吃鱼、虾史人群感染率较高（33.15%）。结论 江西省华支睾吸虫感染除信丰县呈现区域聚集性外，其余呈现散发分布，有必要继续开展全省寄生虫病筛查，同时要对信丰县华支睾吸虫病流行区加强综合性防治。
