Pre-school-aged children are always excluded in mass intervention policies for control of soil-transmitted helminths in Nigera. The need for evidence on infectivity of children in this age group cannot be overemphasized. This study seeks to determine the prevalence of STH among 103 children who are less than 2 years of age in an urban and rural area of Ogun State, Nigeria. This study through questionnaire administration also obtained relevant demographic information and hygiene behavior from parents of children recruited to this study. The overall prevalence of 69.9% was recorded, with Ascaris lumbricoides occurring as the most prevalent helminth (68.0%). This was followed by Hook worm (49.5%) and Trichris trichuria (18.5%). A significant increase in prevalence of hookworm was observed with increase in age (p < 0.05). Generally, A. Lumbricoides was found to be more prevalent as a single infection in the study population. Most of the T. Trichuria and hookworm infections were either in co-infections infections with A. Lumbricoides. The prevalence of A. Lumbricoides and Hookworm were significantly high in rural community when compared with urban (p < 0.05). Poor hygiene practices were common among the study participants. The prevalence of STH infection is incredibly high in this age group that was for a long time considered as less important when it comes to burden due to STH. Therefore, there is a need to include them into future plans for control interventions.

尼日利亚奥贡州城乡 2 岁以下儿童的土壤传播蠕虫感染流行率：控制策略的意义

在尼日利亚，学龄前儿童总是被排除在控制土壤传播蠕虫的大规模干预政策之外。对该年龄组儿童的传染性证据的需求怎么强调都不为过。本研究旨在确定尼日利亚奥贡州城乡地区 103 名 2 岁以下儿童的 STH 患病率。这项研究通过问卷管理还从招募到本研究的儿童的父母那里获得了相关的人口统计信息和卫生行为。记录的总流行率为 69.9%，其中蛔虫是最流行的蠕虫（68.0%）。紧随其后的是钩虫（49.5%）和鞭毛虫（18.5%）。随着年龄的增加，钩虫的患病率显着增加（p < 0.05）。一般来说，A. 在研究人群中，蚯蚓被认为是单一感染更为普遍。大多数 T. Trichuria 和钩虫感染要么与 A. Lumbricoides 合并感染。与城市相比，农村社区的蚧壳虫和钩虫的患病率显着高于城市（p < 0.05）。不良的卫生习惯在研究参与者中很常见。在这个年龄组中，STH 感染的患病率非常高，长期以来，在 STH 造成的负担方面被认为不太重要。因此，有必要将它们纳入未来的控制干预计划。与城市相比，农村社区的蛲虫和钩虫显着增加（p < 0.05）。不良的卫生习惯在研究参与者中很常见。在这个年龄组中，STH 感染的患病率非常高，长期以来，在 STH 造成的负担方面被认为不太重要。因此，有必要将它们纳入未来的控制干预计划。与城市相比，农村社区的蛲虫和钩虫显着增加（p < 0.05）。不良的卫生习惯在研究参与者中很常见。在这个年龄组中，STH 感染的患病率非常高，长期以来，在 STH 造成的负担方面被认为不太重要。因此，有必要将它们纳入未来的控制干预计划。
