Schistosomiasis and soil-transmitted helminthiases (STH) are two parasitic diseases mainly affecting school children. The purpose of this study was to estimate the current prevalence and infection intensity, in addition to the associations of these infections with age and sex, in children aged 4-17 years living in Osun State, Nigeria. From each participant (250 children), one urine and one stool sample were taken for the study, for the microscopic detection of eggs or larvae in faeces by means of the Kato-Katz method and eggs in filtrated urine. The overall prevalence of urinary schistosomiasis was 15.20%, with light infection. The intestinal helminthic species identified (and their prevalence) were (10.80%), (8%), (7.20%), hookworm (1.20%), and (0.4%), all of them being classified as light infections. Single infections (67.95%) are more frequent than multiple infections (32.05%). With this study, schistosomiasis and STH are still endemic in Osun State, but with a light to moderate prevalence and light infection intensity. Urinary infection was the most prevalent, with higher prevalence in children over 10 years. The >10 years age group had the highest prevalence for all of the intestinal helminths. There were no statistically significant associations between gender and age and urogenital or intestinal parasites.
血吸虫病和土壤传播的蠕虫病（STH）是两种主要影响学龄儿童的寄生虫病。本研究的目的是估计尼日利亚奥孙州4至17岁儿童中这些感染的当前流行率和感染强度，以及这些感染与年龄和性别的关联。从每位参与者（250名儿童）采集一份尿液和一份粪便样本用于研究，通过加藤厚涂片法显微镜检测粪便中的虫卵或幼虫以及过滤尿液中的虫卵。泌尿血吸虫病的总体流行率为15.20%，为轻度感染。鉴定出的肠道蠕虫种类（及其流行率）分别为蛔虫（10.80%）、鞭虫（8%）、十二指肠钩虫（7.20%）、钩虫（1.20%）和姜片虫（0.4%），所有这些均被归类为轻度感染。单一感染（67.95%）比多重感染（32.05%）更常见。通过本研究发现，血吸虫病和土壤传播的蠕虫病在奥孙州仍然是地方病，但流行率为轻度至中度，感染强度为轻度。泌尿系统感染最为普遍，10岁以上儿童的患病率更高。10岁以上年龄组所有肠道蠕虫的患病率最高。性别和年龄与泌尿生殖系统或肠道寄生虫之间无统计学显著关联。
