Helminthic and intestinal protozoan infections and malaria infections are common in children less than 15 yr old in sub-Saharan Africa, but little is known about these infections in Guinea. The aim of this study was to determine the prevalence of parasitic infections in children aged less than 15 yr and the relationship of these infections with anemia. The cross-sectional study was done in Dabbis sub-prefecture in the Boke region of Guinea from 18 to 26 March 2017. A simple random sampling at the household level was performed, and 1 child under the age of 15 was included per eligible household. A total of 392 children were included in the analysis. Clinical and parasitological information were assessed, including anthropometric measures (weight and height), disease symptoms, hemoglobin level, and malaria parasitemia. Helminthic and protozoan intestinal infections were present in 59.7% of the children surveyed. Malaria infection prevalence was 45.5% when assessed by microscopy and 43.6% when assessed by a rapid diagnostic test. Plasmodium falciparum, accounting for 84.2% of malaria infections, was the main malaria species infection. Gastrointestinal parasites were present in 19.1% of children. The main gastrointestinal parasites present included Entamoeba coli (5.4%) and Giardia intestinalis (5.1%). There was no association between the presence of anemia and the parasitic status of the children. Parasitic screening and mass treatment in this age group, as well as household awareness raising, would reduce cases of parasitic infections in rural Guinea.

蠕虫和肠道原生动物感染以及疟疾感染在撒哈拉以南非洲不到 15 岁的儿童中很常见，但在几内亚对这些感染知之甚少。本研究的目的是确定 15 岁以下儿童寄生虫感染的患病率以及这些感染与贫血的关系。横断面研究于 2017 年 3 月 18 日至 26 日在几内亚博克地区的达比斯县进行。在家庭层面进行了简单随机抽样，每个符合条件的家庭包括 1 名 15 岁以下的儿童。共有 392 名儿童被纳入分析。评估了临床和寄生虫学信息，包括人体测量指标（体重和身高）、疾病症状、血红蛋白水平和疟原虫血症。接受调查的儿童中有 59.7% 存在蠕虫和原生动物肠道感染。通过显微镜评估疟疾感染率为 45.5%，通过快速诊断测试评估为 43.6%。恶性疟原虫占疟疾感染的84.2%，是主要的疟原虫感染。19.1% 的儿童存在胃肠道寄生虫。存在的主要胃肠道寄生虫包括内阿米巴大肠杆菌（5.4%）和贾第鞭毛虫（5.1%）。贫血的存在与儿童的寄生虫状况之间没有关联。这个年龄组的寄生虫筛查和大规模治疗，以及提高家庭意识，将减少几内亚农村的寄生虫感染病例。
