在西非，贝宁、布基纳法索、加纳、象牙海岸、塞内加尔和多哥报告了猪和人的猪带绦虫囊虫病，尽管缺乏官方数据，但预计其他西非国家的大部分养猪地区也存在猪带绦虫。在尼日利亚的某些地区，猪囊虫病和人带绦虫病的流行率相当高（分别为20.5%和8.6%）。然而，令人惊讶的是，尽管癫痫非常常见，但没有人类囊虫病的病例报告。仅在多哥和贝宁进行了大规模流行病学调查，这两个国家的人类囊虫病流行率分别为2.4%和1.3%。在中非，猪囊虫病和人囊虫病在卢旺达、布隆迪、刚果民主共和国和喀麦隆是（高度）地方病。据报道，乍得和安哥拉的猪也出现了这种寄生虫。囊虫病已被证明是喀麦隆癫痫的主要原因之一，高达44.6%。喀麦隆是对绦虫病-囊虫病复合体进行更详细研究的少数国家之一。在喀麦隆西部省，大规模调查显示，0.4-3%的当地人口和11%的村庄猪中存在活动性囊虫病。然而，成人猪弓形虫的患病率仅为0.1%，这强调了猪弓形虫的频率。氦悖论根据现有资料，一项非常保守的经济估计表明，10个西非和中非国家每年因猪囊虫病造成的损失约为2 500万欧元。人类囊虫病造成的经济损失很难估计，但肯定超过了这一疾病的社会影响，特别是因为许多非洲社区对癫痫病有特殊的认识。结论：T.由于屠宰场数据不可靠以及公共卫生部门缺乏认识和诊断设施，中非和西非猪和人的猪囊虫病发病率仍然被低估。(C)2003 Elsevier Science B.

In West Africa, Taenia solium cysticercosis in both pigs and man has been reported in Benin, Burkina-Faso, Ghana, Ivory Coast, Senegal and Togo, and although official data are lacking, T solium is anticipated to be present in most of the pig-raising regions of other West African countries as well. In some regions of Nigeria, the prevalence of porcine cysticercosis and human taeniosis is quite high (20.5 and 8.6%, respectively). Surprisingly, however, no cases of human cysticercosis have been reported, although epilepsy is very common. Large epidemiological surveys have only been carried out in Togo and Benin, where the prevalence of human cysticercosis was 2.4 and 1.3%, respectively. In Central Africa, porcine and human cysticercosis are (hyper)-endemic in Rwanda, Burundi, the Democratic Republic of Congo and Cameroon. The parasite also has been reported in pigs in Chad and Angola. Cysticercosis has been shown to be one of the major causes of epilepsy in Cameroon with figures as high as 44.6%. Cameroon is one of the few countries where the taeniosis-cysticercosis complex has been examined more in detail. In the Western province of Cameroon large scale surveys have shown that active cysticercosis is present in 0.4-3% of the local population and in 11% of the village pigs. However, the prevalence of adult T solium was only 0.1%, which underscores the frequency of the T. solium paradox. Based on the available information, a very conservative economic estimate indicates that the annual losses due to porcine cysticercosis in 10 West and Central African countries amount to about 25 million Euro. The financial losses due to human cysticercosis are very difficult to estimate, but are certainly exceeded by the social impact of the disease, especially because of the particular perception of epilepsy in many African communities. It is concluded that the true prevalence of T. solium cysticercosis in pigs and humans in Central and West Africa remains underestimated because of unreliable slaughterhouse data and the lack of awareness and diagnostic facilities in the public health sector.
