A study was carried out on 218 school children, aged 6-15 years; on 38 local dry cleaners, aged 25-47 years; and on 57 vehicle washers, aged 18-28 years, who were in frequent contact with a stream from an abandoned fish farm in Ibadan, Oyo State of Nigeria to determine the presence, prevalence and intensity of urinary schistosomiasis. Of the three categories examined for urinary schistosomiasis, school children had the highest prevalence (21.1%); followed by local dry cleaners at 18.4% and vehicle washers at 15.8%. Males among school children and vehicles washers were more infected at 24.8% and 15.8% respectively, while females among dry cleaners had more infection, 25.9%. Most of infected Nigerians had light infection (less than 50 S. haematobium eggs per 10 ml of urine). Eggs of S. mansoni were detected in urine of two male school children. These data show that prevalence and intensity of urinary schistosomiasis is directly dependent on frequency and duration of water contact and age, but independent of sex.
对218名6至15岁的学童、38名25至47岁的当地干洗工以及57名18至28岁的洗车工进行了一项研究，这些人经常接触尼日利亚奥约州伊巴丹一个废弃养鱼场的溪流，以确定泌尿血吸虫病的存在、流行率和感染强度。在接受泌尿血吸虫病检查的三类人群中，学童的流行率最高（21.1%）；其次是当地干洗工，为18.4%，洗车工为15.8%。学童和洗车工中的男性感染率更高，分别为24.8%和15.8%，而干洗工中的女性感染率更高，为25.9%。大多数感染的尼日利亚人感染程度较轻（每10毫升尿液中埃及血吸虫卵少于50个）。在两名男学童的尿液中检测到曼氏血吸虫卵。这些数据表明，泌尿血吸虫病的流行率和感染强度直接取决于与水接触的频率和持续时间以及年龄，但与性别无关。
