2015年青海省平安县土源性线虫病调查结果分析

Survey of Soil-borne Nemathelminthiasis in Pingan County,Qinghai Province,2015

目的掌握土源性线虫病在青海省平安县的流行动态及流行规律,为制定该地区土源性线虫病防治策略与措施提供科学依据。方法平安县内选择一个调查点,采用一粪三检的改良加藤厚涂片法,检查土源性线虫卵;对3~12岁儿童加做透明胶纸肛拭法检查蛲虫卵;采用镜检法镜检并计数土壤中蛔虫卵。使用Excel软件建立数据库,应用SPSS 17.0软件对监测资料进行统计学分析。结果本次人群调查共调查1 001人,总感染率为3.40%,全部为蛔虫感染。其中以学生感染率为最高(6.09%);其次为农民(3.21%);散居儿童等其他10种职业人群中未发现感染者;土壤调查共采集了10户居民庭院、厨房、菜园及厕所的土壤共40份,发现阳性土壤9份,阳性率为22.5%。结论该地区人群中仍存在土源性线虫的感染,主要以儿童为主,土壤监测环境中存在虫卵的污染是人群土源性线虫感染的风险因素,应加强对当地群众的卫生宣传,尤其对儿童的教育力度,使之养成良好的卫生习惯,有效控制土源性线虫病的传播。

Objective To find out the epidemic trend and pattern of soil-borne nemathelminthiasis in Pingan County Qinghai Province,and to provide the scientific basis to formulate the strategy and method to prevent soil-borne nemathelminthiasis.Methods One place was chosen for survey in Pingan County.Modified Kato-Katz thick smear method was used to detect worm eggs.Cellophane tape swab techniques were also used to detect pinworm eggs for the children from 3to 12 years old.The microscopy was used to count the number of ascaris lumbricoides fertilized or unfertilized eggs in the soil.Excel was used to establish the database,and the SPSS 17.0software was used to analyze those data.Results The 1 001 persons were checked and total infection rate was 3.40%,all of them were ascaris infection.The results of different occupation survey showed that：the students got the highest rate of infection（6.09%）,the next were farmers（3.21%）;there was no infected case found among another 10 groups,included those children who were babysat at home.The soils for survey were collected from ten different houses,courtyards,gardens,kitchens and lavatories;nine of them were found to be positive,the positive rate was 22.5%.Conclusion The ascaris infection still existed in the survey area,mainly on children.And the infected soil was the mainly risk which could cause the people attacked.To educate the public on health knowledge should be promoted more,especially to children,help them keep good health habit,then the spread of soil borne nematode disease will be controlled effectively.
