本研究通过调查进一步内陆桑迪土壤隔离区的寄生虫发生情况，扩展了夸祖鲁-纳塔尔和桑迪沿海平原钩虫传播之间的关联。在选定的内陆桑迪地区和以粘土为主的周边地区，在海拔500至700米的狭窄范围内进行了以学校为基础的流行率调查，以减少海拔对气候相关因素（降雨和温度）的影响。为便于比较，分析中包括了位于沿海平原的桑迪。从每个地点采集土壤样本（0-50毫米深），以评估其线虫含量，并分析选定的物理和化学特性。内陆桑迪土壤地区儿童钩虫中度感染率（17.3%）与周边非桑迪土壤地区儿童钩虫低度感染率（5.3%）比较，差异有显著性（P
This study extended the association between hookworm transmission in KwaZulu-Natal and the sandy coastal plain by investigating the parasite's occurrence in isolated areas of sandy soils further inland. A school-based prevalence survey was carried out in selected inland sandy areas and in surrounding areas dominated by clay soils within a narrow altitudinal range of between 500 and 700 in to reduce the effect of altitude on climate-related factors (rainfall and temperature). Sandy areas situated on the coastal plain were included in the analysis for comparative purposes. Soil samples (0-50 mm depth) were collected from each locality to assess their nematode loadings and to analyse selected physical and chemical properties. Significant differences were found between the moderate prevalence of hookworm infection among children living in inland areas with sandy soils (17.3%) and the low prevalence in surrounding non-sandy areas (5.3%, P
