In 1998, the African Programme for Onchocerciasis Control (APOC) decided to launch a long-term impact assessment of its operations. This paper reports the baseline entomological data collected throughout a whole year in two sites of Cameroon (Kahn and Bolo). The Simulium populations of the two study sites were characterized by parous rates of 7.2% and 33.5% respectively and infectivity by O. volvulus of 31 and 190 infective larvae per 1000 parous flies respectively The Annual Transmission Potentials (ATP) were respectively 523 and 9972 infective larvae per man and per year in Kahn and in Bolo. The Simulium populations studied in both sites, even though the ATP in Kahn is 19 times lower than that of Bolo, showed a pattern of an onchocerciasis hyperendemic zone in terms of vector capacities and entomological indices.
1998年,非洲盘尾丝虫病控制规划(APOC)决定对其业务开展长期影响评估。本文报告了在喀麦隆两个地点(卡恩和博洛)全年收集的基线昆虫学数据。两个研究地点的蚋种群特征分别为:产过卵的雌蚋比例分别为7.2%和33.5%,每1000只产过卵的蚋中感染盘尾丝虫的幼虫分别为31条和190条。卡恩和博洛的年传播潜力(ATP)分别为每人每年523条和9972条感染性幼虫。两个地点研究的蚋种群,尽管卡恩的ATP比博洛低19倍,但就媒介能力和昆虫学指标而言,均呈现盘尾丝虫病高度流行区的模式。
