肠道寄生虫在尼加拉瓜似乎很普遍，这促使开展更广泛的患病率研究，其中考虑了拥挤程度、供水质量、地板类型和排泄物处理等社会经济条件。该研究对来自莱昂市约 8% 的市民的 1267 份粪便样本进行了研究。 1267人中肠道致病寄生虫的总体患病率为47.2%。溶组织内阿米巴/迪斯帕的患病率为 18.6%，其次是贾第鞭毛虫 (15.9%) 和蛔虫 (13.4%)。其他蠕虫如钩虫和类圆线虫。被发现的比率非常低。与蠕虫感染不同，贾第鞭毛虫在 5 岁以下的儿童中已经很流行。溶组织内阿米巴/迪斯帕随着年龄的增长而增加，并保持在较高水平。在 595 名肠道寄生虫感染者中，81% 的人生活条件“贫困”，在 13 个家庭群中，社会经济条件良好的家庭寄生虫患病率较低。然而，有几个变量似乎对于确定所遇到的个体肠道原生动物和蠕虫的流行率很重要。 (C) 1997 Elsevier Science B.V.
Intestinal parasites appear to be prevalent in Nicaragua, which motivated a more extensive prevalence study in which socioeconomic conditions such as degree of crowding, quality of water supply, type of floor and disposal of excretion, were considered. The study was performed on 1267 stool samples from about 8% of the citizens of the city of Leon. The overall prevalence of intestinal pathogenic parasites among the 1267 individuals was found to be 47.2%. The prevalence of Entamoeba histolytica/dispar was 18.6% followed by Giardia (15.9%) and Ascaris (13.4%). Other helminths such as hookworms and Strongyloides sp. were found at very low rates. Giardia, in contrast to worm infections, was prevalent already in children under 5 years of age. E. histolytica/dispar increased with age and remained high. Of 595 individuals with intestinal parasites 81% were living in 'poor' conditions and in 13 clusters of households, a lower prevalence of parasites was seen in households characterised as having good socioeconomic conditions. However, several variables appear to be important in determining the prevalence of the individual intestinal protozoa and helminths encountered. (C) 1997 Elsevier Science B.V.
