In 2 periods 1986/'87 and 1987/'88 1193 school children (5-19 years) from 13 randomly selected villages in the Ketu district, Ghana, were examined for Schistosoma haematobium (SH) in the urine. For the egg count the quantitative urine filtration technique was used and besides 3 indirect indicators of SH infection were evaluated. An arbitrary division was made into areas of high and low endemicity, showing SH prevalence rates of 54.3-23.0% and 2.3-16.0%, respectively. The condition of the "dams' in the different areas seemed to influence the infection rates. For all areas both prevalence and intensity of infection were both higher in boys than in girls. In the area of high endemicity it was possible to detect 99% of the heavily infected children (greater than or equal to 100 eggs/10 ml urine) by using the 3 indirect indicators combined.
在1986/87年和1987/88年这两个时间段，对来自加纳凯图区13个随机挑选村庄的1193名学童（5 - 19岁）进行了尿液血吸虫检查。采用定量尿液过滤技术进行虫卵计数，此外还评估了3种血吸虫感染的间接指标。将这些地区任意划分为高流行区和低流行区，高流行区和低流行区的血吸虫患病率分别为54.3% - 23.0%和2.3% - 16.0%。不同地区“水坝”的状况似乎影响感染率。在所有地区，男孩的患病率和感染强度均高于女孩。在高流行区，联合使用3种间接指标能够检测出99%的重度感染儿童（尿中虫卵数≥100个/10毫升）。
