A rapid and cheap method for mapping the endemicity levels of onchocerciasis in both forest and savanna areas, where the vectors are members of the Simulium damnosum complex, is described. The selection of the study communities is based on a general understanding of the vectors' ecology and biassed towards those at highest risk of onchocerciasis, although there must be adequate geographical coverage. In a case study in Cameroon, prevalences were determined, using the non-invasive nodule palpation technique, in samples, each of 30-50 adult males, from 49 villages in six study areas in Cameroon. The method proved effective in the rapid mapping of onchocerciasis distribution in all areas studied, in which the distribution patterns varied from the classical linear to diffuse, and in one area with an anomalous distribution. The method should prove of value in the design of national onchocerciasis control programmes.
本文描述了一种快速且廉价的方法，用于绘制森林和稀树草原地区盘尾丝虫病的流行程度，这些地区的传播媒介是恶蚋复合体的成员。研究社区的选择基于对传播媒介生态的一般了解，并偏向于盘尾丝虫病风险最高的社区，不过必须有足够的地理覆盖范围。在喀麦隆的一个案例研究中，采用非侵入性结节触诊技术，对喀麦隆六个研究区域49个村庄的样本（每个样本包含30 - 50名成年男性）进行了患病率测定。该方法在所有研究区域盘尾丝虫病分布的快速绘制中被证明是有效的，其中分布模式从经典的线性到扩散型不等，在一个区域还呈现出异常分布。该方法在国家盘尾丝虫病控制项目的设计中应具有价值。
