摘要
目的了解南昌市土源性线虫病国家监测点病情监测结果,以科学制订南昌市寄生虫病防治策略。方法2016-2020年在南昌市南昌县土源性线虫病国家监测点,每年调查不少于1000人份3周岁以上常住居民的粪便样本和25份土壤样本,采用改良加藤厚涂片法检测人群土源性线虫虫卵,试管滤纸培养法进行钩虫虫种鉴定,透明胶纸肛拭法检测3~9周岁儿童蛲虫卵,并对土壤样本进行钩蚴和人蛔虫卵鉴定。结果南昌市土源性线虫病国家监测点2016-2020年土源性线虫总感染率为0.93%(47/5054),各年感染率分别为0.10%(1/1000)、2.94%(30/1021)、0.79%(8/1008)、0.50%(5/1002)和0.29%(3/1023),钩虫、蛔虫和鞭虫感染率分别为0.42%(21/5054)、0.02%(1/5054)和0.49%(25/5054),轻度感染者占97.87%(46/47)。人群分布特征显示,不同文化程度间土源性线虫感染率比较差异有统计学意义(χ^(2)=18.06,P=0.001),不同性别、年龄、职业间感染率比较差异均无统计学意义(χ^(2)=0.92、2.01、13.60,均P>0.05),其中初中文化人群感染率最高(1.84%,24/1301)。钩蚴培养显示,美洲钩虫占90.48%(19/21);3~9周岁儿童蛲虫感染率、土壤钩蚴和人蛔虫卵污染率均为0。结论南昌市土源性线虫病国家监测点病情呈低度流行趋势,鞭虫和钩虫是今后南昌市重点关注土源性线虫虫种。
Objective To study the surveillance results of soil-transmitted nematode(STN)disease at the national surveillance site in Nanchang City,so as to scientifically formulate prevention and control strategies for parasitic diseases in Nanchang City.Methods From 2016 to 2020,in Nanchang County,the national surveillance site of STN disease in Nanchang City,no less than 1000 fecal samples and 25 soil samples of permanent residents over 3 years of age were investigated annually.The improved Kato-Katz thick smear method was used to detect the eggs of STN in the population,species identification of hookworm was carried out by test-tube filter paper incubation,the Enterobius vermicularis eggs of 3-9 years old children were detected by cellophane anal swab method,and the soil samples were used to identify hookworm larvae and of Ascaris lumbricoides eggs.Results The total infection rate of STN was 0.93%(47/5054)from 2016 to 2020 in the national surveillance site of Nanchang City.The annual infection rates were 0.10%(1/1000),2.94%(30/1021),0.79%(8/1008),0.50%(5/1002)and 0.29%(3/1023),respectively;the infection rates of hookworm,Ascaris lumbricoides and Trichuris trichiura were 0.42%(21/5054),0.02%(1/5054)and 0.49%(25/5054),respectively.Totally 97.87%(46/47)of the infected persons were mild infection.The population distribution characteristics showed that there was significant difference in STN infection rate among different education levels(χ^(2)=18.06,P=0.001),but there was no significant difference in infection rate among different sex,age and occupation(χ^(2)=0.92,2.01,13.60,P>0.05).Among them,the infection rate of junior high school cultural was the highest(1.84%,24/1301).The culture of hookworm larvae showed that 90.48%(19/21)were Necator americanus;the infection rate of Enterobius vermicularis in 3-9 years old children,the contamination rate of soil hookworm larvae and Ascaris lumbricoides eggs,were all 0.Conclusion STN disease shows a low prevalence trend at the national monitoring site in Nanchang City,Trichuris trich
