Urine samples were assayed for urinary schistosomiasis in four local government areas (LGA) of Imo State, Nigeria between May 1998 and September 2000. A total of 3504 persons were sampled, with 880 (25.1%) being positive for urinary schistosomiasis, based on records of eggs of Schistosoma haematobium. The prevalence of S. haematobium infection differed in the various LGAs, with Oguta (38.9%) and Owerri-West (10.4%) showing the highest and the lowest values, respectively. Prevalence was higher in males (67.4%) than in females (32.6%) and in subjects 11-20 years of age (31.5%), while prevalence varied among different occupational groups, with farmers ranking the highest (41.6%). Visible haematuria was the predominant symptom (P<0.05). Of 880 persons positive for eggs of S. haematobium, 452 (51.4%) had visible haematuria, followed by suprapubic pains 214 (24.3%) and painful micturition 97 (11.0%). Although 367 (10. 5%) of the sampled subjects with eggs of S. haematobium showed no visible haematuria, 513 (14.6%) clearly demonstrated haematuria.
1998年5月至2000年9月期间，在尼日利亚伊莫州的四个地方政府辖区（LGA）对尿样进行了血吸虫病检测。共采集了3504人的样本，根据埃及血吸虫卵的记录，880人（25.1%）尿血吸虫病呈阳性。埃及血吸虫感染率在不同的地方政府辖区有所不同，奥古塔（38.9%）和奥韦里西区（10.4%）分别显示出最高和最低值。男性（67.4%）的感染率高于女性（32.6%），11至20岁的受试者感染率为（31.5%），不同职业群体的感染率也有所不同，农民的感染率最高（41.6%）。肉眼血尿是主要症状（P<0.05）。在880名埃及血吸虫卵呈阳性的人中，452人（51.4%）有肉眼血尿，其次是耻骨上疼痛214人（24.3%）和排尿疼痛97人（11.0%）。虽然367名（10.5%）埃及血吸虫卵呈阳性的采样受试者没有肉眼血尿，但513人（14.6%）明显出现血尿。
