在尼日利亚西南部的一个城市社区伊巴丹评估了泌尿血吸虫病的现状。对1331名儿童进行了血吸虫虫卵检查。尿中检出嗜血杆菌，感染率为17.4%。学龄后儿童的患病率（22.4%）显著高于小学生（12.0%）（P < 0.01）。基于每10 ml尿液中虫卵数几何平均数的感染强度在小学后也较高，（36.7个鸡蛋/10毫升尿）比小学生（29.9个鸡蛋/10毫升尿），男孩有一个显着的（P < 0.01）感染率高男性感染率（39.0个/10 ml尿）高于女性（22.1个/10 ml尿）（P < 0.01）。11-15岁年龄组的总体几何平均感染强度最高（38.8个卵/10 ml尿）。42%的受感染儿童排出>50个卵/10 ml尿。2.2%排泄S.尿中有曼氏血吸虫卵。男性接触水的次数（31.8%）明显多于女性（38.2%）（P < 0.01）。共发现9种钉螺，其中以B. (p)globosus是最丰富和广泛的。这些结果表明，尿血吸虫病在伊巴丹仍在积极传播。
The current status of urinary schistosomiasis was assessed in Ibadan, an urban community in south-western Nigeria. Of 1331 children examined for eggs of S. haematobium in their urine, 17.4% were infected. Prevalence in postprimary schoolchildren was significantly (P < 0.01) higher (22.4%) than in primary schoolchildren (12.0%). Intensity of infection based on geometric mean egg count per 10 mi of urine was also higher in postprimary (36.7 eggs/10 mi urine) than primary pupils (29.9 eggs/10 mi urine),Boys had a significantly (P < 0.01) higher infection rate (24.1%) than girls (8.5%), and the intensity of infection was also higher (P < 0.01) in males (39.0 eggs/10 mi urine) than in females (22.1 eggs/10 mi urine). The overall geometric mean intensity of infection was highest (38.8 eggs/10 mi urine) in the 11-15 years age group. 42% of infected children excreted >50 eggs/10 mi urine. 2.2% excreted S. mansoni eggs in urine. Water contact activities were more frequent (P < 0.01) in males (31.8%) than females (38.2%). Nine species of snails were encountered, with B. (p) globosus being the the most abundant and widespread. These results show chat urinary schistosomiasis is still being actively being transmitted in Ibadan.
