2013-2016年合江县土源性线虫监测结果分析
|
摘要
目的了解合江县土源性线虫感染状况和流行规律,为制定土源性线虫感染防制措施提供科学依据。方法采用改良加藤厚涂片法,一粪三检,查钩虫、蛔虫、鞭虫卵和透明胶纸肛试子法查蛲虫卵对监测点的常住居民进行土源性线虫感染情况进行监测。率的比较采用χ~2检验。结果 2013-2016年间,合江县土源性线虫平均感染率为11.41%,其中蛲虫的平均感染率最高(χ~2=634.67,P<0.05);土源性线虫感染总感染率分别为13.80%、10.80%、9.15%和11.90%,整体未呈现显著趋势(χ_(趋势)~2=2.69,P>0.05)。女性的鞭虫感染率(0.78%)高于男性(0.26%)(χ~2=5.17,P<0.05);土源性线虫总感染率随着年龄增加呈增长趋势(χ_(趋势)~2=127.97,P<0.05);非学龄儿童和农民的土源性线虫、钩虫感染率较高,学生较低(P<0.05),非学龄儿童和学生蛔虫感染率较高,农民较低(P<0.05);土源性线虫的总感染率随着文化水平的提高总体呈下降趋势(P<0.05)。结论 2013-2016年合江县土源性线虫感染率总体无下降趋势,不同年龄、性别、文化程度土源性线虫感染率不同。
Objective To understand the infection status and prevalence of soil-transmitted helminths in Hejiang county of Sichuan province so as to provide scientific basis for proposing prevention and control measures. Method We adopted the modified Kato' s thick smear method to conduct the tests 3 times on one fecal sample to check the eggs of ancylostome,ascaris lumbricoides,trichuris trichiura(whipworm).We also used cellophane anal swab technique to survey the prevalence of enterobius vermicularis in local inhabitant at monitoring sites. Chi-square test was used to compare the ratio. Results The average infection rate in Hejiang from 2013 to 2016 was 11.41%, the infection rate of enterobius vermicularis was the highest(χ~2=634.67,P<0.05), the overall infection rate of soil-transmitted helminths was 13.80%, 10.80%, 9.15% and 11.90%, respectively. The rate of overall infection did not show a prominent downtrend(χ_(trend)~2=2.69,P>0.05). The infection rate of trichuris trichiura in female(0.78%) was higher than that in male(0.26%)(χ~2=5.17, P<0.05). The overall infection rate in different age groups showed an increasing trend with the age growing(χ_(trend)~2=127.97, P<0.05). The infection rates of soiltransmitted helminths and ancylostome in children and farmers were higher than that in students(P<0.05), whereas the infection rate of ascaris lumbricoides in children and students was higher than that in farmers(P<0.05). Soil-transmitted helminths infection rate tended to decrease in residents with higher educational level. Conclusion The infection rate of soil-transmitted helminths has not showed a decrease continuously in Hejiang county from 2013 to 2016,the infection rate varies in residents with age,gender and educational level.
