Abstract: Objective To understand and analyze the epidemic status of principal human parasites in Jiangxi Province, so as to provide the evidence for formulating The 13rd Five?Year Project of Parasites Control. Methods A survey was performed according to the scheme of The 3rd National Survey of Principal Human Parasites as well as the specific situation of Jiangxi Province. The survey of the soil?transmitted nematodes and intestinal protozoa were performed based on the ecological regions and stratified by economic and geographic situation. The survey of Clonorchis sinensis was performed along with the soil?transmitted nematodes in rural, and was performed by the sample method of random cluster in cities and towns. Results Totally 23 606 residents of 92 survey sites from 32 counties were surveyed, all of them were tested for the infection of soil?transmitted nematodes, in which 21 569 residents were tested for intestinal protozoa infection, and 1 486 children were tested for eggs of Enterobius vermicularis. Twenty kinds of intestinal parasites were found, with the total infection rate of 9.64%, and 4.296 millions of patients were reckoned in the whole Jiangxi Province. The infection rate of children of E. vermicularis was 13.73%. The infection rates of C. sinensis and intestinal protozoa were 0.58% and 1.42% respectively. The infection rate of Toxoplasma gondii was 7.50%. Conclusion In Jiangxi Province, the infection rates of soil?transmitted nematodes are decreasing but the infection rate of C. sinensis is increasing in local areas, and the control work of parasites still should be strengthened.

摘要： 目的 了解和分析江西省重点寄生虫病的流行现状，并为制定全省“十三五”规划提供科学依据。方法 按照2014年全国第3次人体重点寄生虫感染现状调查方案，结合江西省具体情况开展调查。其中土源性线虫和肠道原虫调查以生态区为基础，按照经济条件和地理方位进行分层整群抽样；华支睾吸虫的调查在农村地区与土源性线虫调查一并进行，在城镇地区以随机整群抽样法进行调查。 结果 在全省32个县的92个调查点共计调查了23 606人，其中21 569人接受了肠道原虫检查，1 486名儿童接受了蛲虫卵检查。全省共查出肠道寄生虫20种，感染率为9.64%，推算全省肠道寄生虫感染者约429.6万人。儿童蛲虫感染率为13.73%，华支睾吸虫感染率为0.58%，肠道原虫感染率为1.42%，目标人群弓形虫阳性率为7.50%。 结论 江西省人群土源性线虫感染率呈下降趋势，华支睾吸虫感染率在局部地区明显上升，全省寄生虫病防治工作仍需加强。
