Investigation and analysis on intestinal parasitic infection in outpatient service of Guigang Center for Disease Control and Prevention from 2016 to 2019

目的了解2016—2019年贵港市居住患者肠道寄生虫感染情况,为开展寄生虫病防制提供科学依据。方法对2016年7月—2019年12月期间贵港市疾控中心初诊的1406例患者采集粪便进行改良加藤厚涂片法镜检,检出寄生虫卵判定为阳性,并予以计数,判定感染强度;≤12岁儿童加用透明胶纸肛拭法检测,抽取资料进行统计学分析。结果共检查1406例患者,肠道蠕虫感染率为37.98%(534/1406),检出蛔虫、钩虫、蛲虫、鞭虫、华支睾吸虫5种肠道蠕虫,感染率分别为蛔虫3.48%(49/1406)、钩虫1.92%(27/1406)、蛲虫2.84%(40/1406)、鞭虫0.78%(11/1406)、华支睾吸虫29.66%(417/1406)。蛔虫、钩虫、蛲虫、鞭虫以儿童、学生和农村妇女感染为主,华支睾吸虫感染率最高为干部职员,感染者以男性、城镇居民、高中/中专学历和>40~50岁组为主。结论华支睾吸虫病是贵港市最多见的寄生虫病,是今后预防和治疗的重点,应加强对重点人群的预防宣传教育,做到早发现、早治疗。

Objective To provide scientific basis for the prevention and control of parasitic diseases in Guigang by understanding intestinal parasitic infections in resident patients of the region from 2016 to 2019.Methods The feces of 1406 newly diagnosed patients from July 2016 to December 2019 were collected for microscopic examination by modified Kato thick smear method.The parasitic eggs were detected and determined as positive,and the infection intensity was determined by counting.The children not greater 12 years old were detected by anal swabs combined with cellophane tape,and the data were extracted for statistical analysis.Results A total of 1406 cases were examined,and the infection rate of intestinal worms was 37.98%(534/1406).Five categories of intestinal worms including Ascaris,Hookworms,Pinworms,Trichuris trichiura and Clonorchis sinensis were detected,the infection rate was 3.48%(49/1406)for Ascaris,1.92%(27/1406)for Hookworms,2.84%(40/1406)for Pinworms,0.78%(11/1406)for Trichuris trichiura,and 29.66%(417/1406)for Clonorchis sinensis.Ascaris,Hookworms,Pinworms and Trichuris trichiura were primarily found in children,students and rural women.The infection rate of Clonorchis sinensis was maximum among cadres and office clerks,major infected persons were male,urban residents,subjects with senior high school/technical secondary school education and>40-50 years old group.Conclusion Clonorchis sinensis is considered to the most common parasitic disease in Guigang,and it is the focus of prevention and treatment in the future.The prevention and education of key population should be intensiified to achieve early detection and treatment.
