目的分析陕西省人群土源性线虫感染的分布现状,为制定防治对策提供依据。方法在陕南、陕北和关中采用分层整群抽样方法,对抽中的村(点)自然人群进行调查,分病种进行病原学检查,并进行统计分析。结果共调查7726人,土源性线虫感染率为18.86%,其中蛔虫、蛲虫、鞭虫、钩虫感染率依次为15.87%、11.46%、0.82%、0.04%;蛔虫感染度构成为轻度感染占97.74%、中度占1.60%、重度占0.66%;鞭虫感染度构成为轻度占88.89%、中度占7.41%、重度占3.70%。结论现陕西省人群土源性线虫感染率与1992年调查结果比较显著下降,感染病例主要分布在农村和中小学校并与文化程度高低关系密切,改善农村居民饮水环境及改变个人生活卫生习惯仍是预防控制人群寄生虫病感染的主要措施。
Objective To analyze the distribution status of soil-borne nematode infection in Shaanxi Province and provide basis for prevention and control measures. Methods Stratified cluster sampling method was used in Southern Shaanxi, Northern Shaanxi and Guanzhong to investigate the natural population of the village (point) in the extraction, carry out etiological examination of the diseased species and make statistical analysis. Results A total of 7726 people were surveyed. The infection rate of soil-borne nematodes was 18.86%. The infection rates of roundworm, pinworm, whipworm and hookworm were 15.87%, 11.46%, 0.82% and 0.04% respectively. The infection rate of roundworm was mild Accounting for 97.74%, moderately accounted for 1.60%, severe accounted for 0.66%; whipworm infection accounted for 88.89% mild, moderate 7.41%, severe accounted for 3.70%. Conclusions The prevalence of soil-borne nematodes in Shaanxi Province is significantly lower than the survey results in 1992. Infection cases are mainly distributed in rural and primary and secondary schools and are closely related to the level of education. Improving drinking water environment and changing personal hygiene in rural areas is still Prevention and control of parasitic infections in the main measures.
