The prevalence of skin depigmentation in the pretibial region is closely correlated in the adult Congolese population with conventional indices (microfilarial index, mean microfilarial density, cyst index) for the evaluation of endemic onchocerciasis. Individuals over 15 years of age in endemic villages who had a microfilarial index of 80-90%, had a cystic index of 60-70% and a pretibial depigmentation index about 20% (30-40% for individuals aged > 50 years). Thus, in Africa, this new evaluation index offers a simple, noninvasive, quick and cheap way to identify areas where the level of endemic onchocerciasis is probably high and which are likely to benefit from an anti-onchocerciasis campaign.
在刚果成年人群中，胫前区皮肤色素脱失的患病率与用于评估盘尾丝虫病流行情况的传统指标（微丝蚴指数、平均微丝蚴密度、囊肿指数）密切相关。在流行村庄中，15岁以上个体的微丝蚴指数为80 - 90%，囊肿指数为60 - 70%，胫前色素脱失指数约为20%（50岁以上个体为30 - 40%）。因此，在非洲，这一新的评估指标提供了一种简单、无创、快速且廉价的方法，用于识别盘尾丝虫病流行程度可能较高且可能受益于抗盘尾丝虫病运动的地区。
