摘要/Abstract

摘要： 目的 :了解未加控制措施干预下农村社区蛔虫感染与传播动态。方法 :由 6次横断面调查组成的一年纵向研究。结果 :当地人群感染率常年稳定在 60 %以上 ,但年内社区感染率与感染度 ( EPG)有显著性波动。年龄分层分析进一步表明 ,感染的波动仅在部分儿童具显著性 ,而在几乎所有成人组波动不具显著性。蛔虫在土壤内的发育率变化与年内月平均温度的变化相一致。结论 :该地蛔虫感染呈相对稳定的地方性传播但存在明显季节波动 ,此种波动与季节对土壤中虫卵发育的影响有关 ,儿童是构成社区蛔虫感染波动的主要人群。

Abstract: AIM:To study the dynamics of Ascaris infection in rural Communities where intervention measurements were not introduced. METHODS:An
one- year longitudinal study consisting of 6 cross-sectional surveys at about two-month interval was carried out. RESULTS: A high prevalence of above 60% throughout the year was found in the area with a significant fluctuation in both prevalence and intensity (EPG) of the communities. Age-stratified analses further indicated that the fluctuation was only found to be significant in some children groups other than adult groups. Changes in monthly development rate of eggs of A.lumbricoides in soil was found in good accordance with the fluctuation of monthly mean temperature in the area during the year. cONCLUSION: The transmission of Ascaris infection in this area was relatively stable but with significant fluctuation in both revalence and in tensity during the year. The fluctuation could be attributed to the seasonal effects on the development of A.lumbricoides eggs in soil. Children were found to be the main population contributing to the fluctuation of Ascaris infection in the communities.

Key words: Ascaris lumbricoides, eggs, prevalence, intensity
