A cross sectional study was carried out from the 6th of June to the 30th of September 2000 in order to determine the areas of transmission of onchocerciasis.
The method of rapid epidemiological mapping of onchocerciasis was used. The villages h ave first been identified on chart of 1/200000, and selected according to a reasoned choice. The sample was composed of 47 villages by geographical area, either 94 villages included in 37 districts of the 10 regions of the country. The survey consisted in a physical exam of 30 to 50 people aged 20 years and more according to a fraction of 1/5, and living since at least 10 years in these villages.
No local cases were found in the northern part of the country. Surveys conducted in the south part of the country were negative in Kouilou and Lékoumou areas and positive in Ndzouengue village of Pool (37.1%), in Kinkoula village of Bouenza (24.2%) and in Ngouele village of Niari (9.1%). Results of our survey confirm the high level of endemicity of onchocerciasis already observed in the previous studies.
This epidemiological study will contribute to involve population in a new strategy of community-directed treatment with ivermectin.
2000年6月6日至9月30日开展了一项横断面研究，以确定盘尾丝虫病的传播区域。
采用盘尾丝虫病快速流行病学绘图方法。首先在1/200000的地图上确定村庄，并根据合理选择进行挑选。样本按地理区域由47个村庄组成，即该国10个地区37个区中的94个村庄。调查包括根据1/5的比例对30至50名20岁及以上、在这些村庄居住至少10年的人进行身体检查。
该国北部未发现本地病例。在该国南部进行的调查中，库伊卢和莱库穆地区结果为阴性，普尔省的恩祖恩盖村（37.1%）、布恩泽省的金库拉村（24.2%）和尼亚里省的恩圭莱村（9.1%）结果为阳性。我们的调查结果证实了先前研究中已观察到的盘尾丝虫病高流行水平。
这项流行病学研究将有助于让民众参与伊维菌素社区定向治疗的新策略。
