Between January and December 1981, parasitological and symptomatological methods of diagnosis were used to survey the prevalence of onchocerciasis among the human population in the Manor area of the Benue State of Nigeria. Hospital records of different health establishment all over the state were also examined to assess the status of the disease in the state. 911 or 69.8% of the 1306 persons examined were positive for microfilariae of Onchocerca volvulus; 135 or 10.3% had visual impairment including total blindness; 377 or 28.7% carried nodules with greater number of nodules found on the lower part, especially on the pelvis, than the upper part of the body. Skin conditions such as intense itching, depigmentation, lichenification and atrophy were regularly found in infected persons. Generally, the incidence was higher in males than females and there was always increased severity with advancing age. Hospital records also show that the infection is widespread in the state. The status of the disease in Manor is discussed and it is concluded that the area is hyperendemic for human onchocerciasis.
1981年1月至12月期间，采用寄生虫学和症状学诊断方法，对尼日利亚贝努埃州马诺尔地区人群中的盘尾丝虫病流行情况进行了调查。还查阅了该州各地不同医疗机构的医院记录，以评估该州的疾病状况。在接受检查的1306人中，911人（占69.8%）盘尾丝虫微丝蚴检测呈阳性；135人（占10.3%）有视力损害，包括全盲；377人（占28.7%）有结节，身体下部尤其是骨盆处的结节数量多于上部。感染人群中经常出现强烈瘙痒、色素沉着、苔藓化和萎缩等皮肤状况。一般来说，男性的发病率高于女性，且随着年龄增长病情总是加重。医院记录还显示，该感染在该州广泛存在。对马诺尔地区的疾病状况进行了讨论，得出该地区是人类盘尾丝虫病高度流行区的结论。
