加纳4个乡村的学龄前儿童中存在11种肠道寄生虫的证据是通过检查粪便样本获得的。这4个村的6种常见感染中，有一部分的患病率有显著差异。蛔虫的流行率从一个村庄(沿海稀树草原的Oshiyie)的约76%到另一个村庄(Akuma，林区)的明显0%不等。没有观察到任何感染的患病率与性别有关。对儿童年龄与患病率关系的调查表明，到儿童4岁时，蛔虫和鞭虫的流行程度已基本持平。没有证据表明这两种内阿米巴的流行。或spp.或者钩虫接近最大值，甚至在年龄最大的孩子中也是如此。这些趋势适用于所有村庄，而不考虑感染流行率值的差异。平均而言，Oshiyie的儿童感染病毒的人数是其他村庄儿童的两倍。对流行数据的调查揭示了两对感染之间存在关联的证据，特别是那些涉及钩虫和毛滴虫的感染。
Evidence for the presence of 11 intestinal parasites in pre-school children form 4 rural villages in Ghana was obtained from an examination of stool samples. Striking differences were detected between the prevalence of some of the 6 common infections in the 4 villages. The prevalence of Ascaris lumbricoides varied from about 76% in one village (Oshiyie, coastal savanna) to apparently 0% in another (Akuma, forest zone). No differences in prevalence for any infection were observed to be sex dependent. Investigation of the relationship between age of the children and prevalence showed that the degree of prevalence of both A. lumbricoides and Trichuris trichiura had essentially levelled off by the time the children were 4 years old. There was no evidence to suggest that the prevalence of either Entamoeba sp. or spp. or hookworm was approaching a maximum value, even in the oldest children. These trends applied across the villages regardless of the differences in prevalence values for the infections. On average the children of Oshiyie were found to harbour twice as many infections as the children of the other villages. The investigation of the prevalence data revealed evidence of associations between pairs of infections, particularly those involving hookworm and T. trichiura.
