The Awa indigenous people of Ecuador live in remote areas and were included in health programs only recently. The first screening for parasitic infections in the Awa communities was implemented in the context of community epidemiology. During the site visits in each community, the health-care staff collected the samples for stool microscopy and serology for . A total of 705 individuals consented for the study, representing 40% of the Awa population living in the targeted communities; 184 (26%) participants supplied a stool sample. was found in about 11% of samples. Prevalence of and was 54.9% and 36.9%, respectively. No hookworm eggs were found. In addition, larvae were found in eight individuals (4.3%), whereas serology was positive in 22.7% of the individuals tested. The community-based approach resulted in an impressive participation. There was a high prevalence of parasites associated with relevant morbidity.
厄瓜多尔的阿瓦原住民生活在偏远地区，直到最近才被纳入卫生计划。首次在阿瓦社区开展寄生虫感染筛查是在社区流行病学背景下进行的。在每个社区的现场访问期间，医护人员收集粪便显微镜检查和血清学检查的样本，用于检测 。共有 705 人同意参与研究，占居住在目标社区的阿瓦人口的 40%；184 人（26%）提供了粪便样本。在大约 11%的样本中发现了 。和 的患病率分别为 54.9%和 36.9%。未发现钩虫卵。此外，在 8 个人（4.3%）中发现了 幼虫，而在接受检测的个体中，有 22.7%的血清学呈阳性。基于社区的方法获得了令人瞩目的参与度。与相关发病率相关的寄生虫患病率很高。
