Soil-transmitted nemathelminth, intestinal protozoa and Enterobius vermicularis were investigated by the Kato-Katz technique (a fecal sample seized two), iodine smear method and cellophane tape method, respectively. Meanwhile a questionnaire survey was conducted on the basic situation, knowledge and health behaviors of the residents to soiltransmitted nemathelminth infection. RESULTS: Totally 1 023 residents were investigated, and 38 were positive of parasitic infection, with the total infection rate of 3.71%. The soil-transmitted nematodes infection rate was 3.62%, 36 people were infected with hookworm (3.52%), one person was infected with Trichuris trichiura (0.10%), one person was infected with intestinal protozoa (Blastocystis hominis). Ascaris lumbricoides, E. vermicularis and tapeworm infections were not founded. The total awareness rate of prevention knowledge, behavior and attitude was 76.93%. CONCLUSIONS: The infection rate of soil-transmitted nemathelminth infections is reduced below 5% in Tongcheng City. The main species of parasites is Necator americanus, and the population of the infection is mainly concentrated in the residents over the age of 60 years. ［摘要］目的 了解桐城市重点寄生虫病的流行状况, 为“十三五”寄生虫病防治规划的科学制定提供流行病学依据。 方法 在桐城市抽取不同层次的调查点, 调查≥ 3岁的居民重点寄生虫感染情况。土源性线虫病调查采用Kato-Katz法 (1粪2检), 肠道原虫感染采用碘液涂片法, 儿童采用透明胶纸法检查蛲虫, 同时还进行调查点基本情况、土源性线虫病 防治知识及健康行为的问卷调查。 结果 本次共调查居民1 023人, 检获寄生虫感染阳性38人, 总感染率为3.71%, 土源 性线虫总感染率为3.62%。其中钩虫感染36人, 感染率3.52%; 鞭虫感染1人, 感染率0.10%; 肠道原虫感染1人 (人芽囊 原虫); 未发现蛔虫、蛲虫和绦虫感染。防治知识、行为、态度总知晓率为76.93%。 结论 桐城市土源性寄生虫感染率降 至5%以下, 虫种主要以美洲钩虫为主, 感染者主要集中在60岁以上居民。.
