先前的研究结果表明，在南非夸祖鲁-纳塔尔省，美洲板口线虫和粪圆线虫仅是沿海低地的特有种。这些蠕虫以及鞭虫和蛔虫的流行情况现已在从莫桑比克边境（南纬 26 度 57 英尺）到东开普省边界（南纬 30 度 53 英尺）的沿海平原 1000 公里长的横断面（海拔 < 300 m）进行了调查。美洲钩虫是迄今为止最主要的钩虫种类。尽管美洲猪笼草和粪圆线虫感染的流行率随着南纬度的增加而降低，但毛毛虫和蚓螈的感染率却没有下降。这些分布模式的决定因素根据一系列与温度和降雨相关的变量进行检查。
The results of a previous study indicated that, in the province of KwaZulu-Natal, South Africa, Necator americanus and Strongyloides stercoralis were endemic to the coastal lowlands only. The prevalences of these helminths, as well as those of Trichuris trichiura and Ascaris lumbricoides, have now been investigated along a 1000-km-long transect through the coastal plain, at altitudes of < 300 m, from the Mozambique border (26 degrees 57'S) to the border with Eastern Cape province (30 degrees 53'S). Necator americanus was by far the most dominant hookworm species. Although prevalences of N. americanus and S. stercoralis infection decreased with increasing southerly latitude, those of T. trichiura and A. lumbricoides did not. Determinants of these distribution patterns are examined in terms of a suite of temperature- and rainfall-related variables.
