To understand the current prevalence of clonorchiasis in Jiangxi Province.
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 was carried out together with the soil-transmitted helminths investigation, and in the urban areas, the random cluster sampling method was applied for the investigation. There were 92 survey sites from 32 counties. The eggs of in stool were examined by Kato-Katz technique, and health knowledge was also investigated by questionnaires in some people at the same time.
A total of 23 606 sample residents were investigated, and 138 were found infected with , with the infection rate of 0.58%. Light infection was found in most of them. Totally 124 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 (＜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%.
The distribution of 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.
了解江西省华支睾吸虫病的流行现状。
按照江西省第三次人体重要寄生虫病调查方案进行调查。根据生态区域，按经济地理状况采用分层整群抽样方法。在农村地区，华支睾吸虫病调查与土源性线虫病调查一并进行，在城区采用随机整群抽样方法进行华支睾吸虫病调查。来自32个县的92个调查点。粪便中华支睾吸虫虫卵采用改良加藤厚涂片法检查，同时对部分人群进行问卷调查了解卫生知识。
共调查23606名居民，发现华支睾吸虫感染者138例，感染率为0.58%。大部分为轻度感染。124例感染者集中在信丰县，其他县仅有少数感染者。在信丰县，共调查851名居民。除0岁组外各年龄组均有感染者，感染率最高的是70岁组（24.00%）。男性感染率为20.29%，高于女性（6.25%），差异有统计学意义（＜0.01）。文化程度为高中或中专者感染率最高（31.48%）。职业分布中，公职人员感染率最高（39.39%）。问卷调查显示，信丰县有生食鱼或虾史人群的感染率为33.15%。
华支睾吸虫感染在信丰县呈区域性聚集分布，其他地区呈散在分布。需继续开展寄生虫病筛查，在信丰县需加强综合防控干预。
