Abstract

The prevalence of onchocercosis was determined in three Local Government Areas (Ezeagu, Oji-River and Uzo-Uwani) in Enugu State, Eastern Nigeria between March 1989 and June 1990. Enugu State was shown to be mesoendemic for onchocercosis. A total of 7472 (26.9%) persons out of 27,831 examined were positive for skin microfilariae. There was no significant difference in infection rates between males (27.6%) and females (26.2%). Of the 118 villages surveyed only five had no inhabitant with skin microfilariae. There was a progressive increase of prevalence to the second decade of life, although 96.6% of cases with skin microfilariae had only a light infection. Onchocercomata prevalence was recorded as 27.3% which tallies with the prevalence of skin microfilariae at 26.9% hence onchocercomata prevalence may be used as a yardstick for predicting skin microfilariae prevalence.

摘要

1989年3月至1990年6月期间，在尼日利亚东部埃努古州的三个地方政府辖区（埃泽阿古、奥吉河和乌佐-乌瓦尼）确定了盘尾丝虫病的流行情况。埃努古州被证明是盘尾丝虫病的中度流行地区。在接受检查的27831人中，共有7472人（26.9%）皮肤微丝蚴呈阳性。男性（27.6%）和女性（26.2%）的感染率没有显著差异。在调查的118个村庄中，只有5个村庄没有皮肤微丝蚴感染者。患病率在生命的第二个十年呈逐渐上升趋势，尽管96.6%的皮肤微丝蚴病例仅有轻度感染。盘尾丝虫瘤患病率记录为27.3%，与皮肤微丝蚴患病率26.9%相符，因此盘尾丝虫瘤患病率可作为预测皮肤微丝蚴患病率的一个标准。
