is widely distributed in the tropics and subtropics. The aim of this study was to determine the prevalence of and other intestinal parasites and identify the risk factors for infection with in a rural area of Angola. A cross-sectional study was conducted in school-age children (SAC) in Cubal, Angola. A questionnaire collecting clinical and epidemiological variables was used, and two stool samples were collected. A concentration technique (Ritchie) and a technique for detection of larvae migration (Baermann) were performed. Of 230 SAC, 56.1% were female and the mean age was 9.3 years (SD 2.45). Severe malnutrition, according to body mass index (BMI)-for-age, was observed in 20.4% of the SAC, and anemia was found in 59.6%. was observed in 28 of the 230 (12.8%) SAC. Eggs of other helminths were observed in 51 (22.2%) students: spp. in 27 students (11.7%), hookworm in 14 (6.1%), four (1.7%), in four (1.7%), in three (1.3%), spp. in two (0.9%), and one (0.4%). Protozoa were observed in 17 (7.4%) students. Detection of was higher using the Baermann technique versus using formol-ether (11.3 vs. 3%). Overall prevalence of in the school population of 16 studied schools in the municipal area of Cubal was greater than 10%. This fact must be considered when designing deworming mass campaigns. The use of specific tests in larvae detection is needed to avoid overlooking this parasite.
广泛分布于热带和亚热带地区。本研究的目的是确定安哥拉某农村地区[寄生虫名称未给出]及其他肠道寄生虫的流行情况，并确定感染[寄生虫名称未给出]的危险因素。在安哥拉库巴尔的学龄儿童中进行了一项横断面研究。使用了一份收集临床和流行病学变量的问卷，并采集了两份粪便样本。采用了浓缩技术（里奇法）和幼虫迁移检测技术（贝尔曼法）。在230名学龄儿童中，56.1%为女性，平均年龄为9.3岁（标准差2.45）。根据年龄别体重指数（BMI），20.4%的学龄儿童存在严重营养不良，59.6%的儿童患有贫血。在230名学龄儿童中有28名（12.8%）检测到[寄生虫名称未给出]。在51名（22.2%）学生中观察到其他蠕虫的虫卵：27名学生（11.7%）感染蛔虫属，14名（6.1%）感染钩虫，4名（1.7%）感染鞭虫，4名（1.7%）感染蛲虫，3名（1.3%）感染姜片虫，2名（0.9%）感染绦虫属，1名（0.4%）感染吸虫。在17名（7.4%）学生中观察到原生动物。与甲醛乙醚法相比，使用贝尔曼技术检测[寄生虫名称未给出]的检出率更高（11.3%对3%）。在库巴尔市16所研究学校的在校学生中，[寄生虫名称未给出]的总体流行率超过10%。在设计大规模驱虫运动时必须考虑到这一事实。需要使用特定的幼虫检测试验以避免漏检这种寄生虫。
