Globalization has pushed population movements in the last decades, turning imported diseases into the focus. Due to behavioral habits, children are at higher risk of acquiring parasitosis. This study aims to investigate the prevalence of parasites in migrant children and factors associated with parasitic diseases.
Retrospective cross-sectional study (2014-2018) including children diagnosed with parasitosis. The diagnosis was based on serology and/or microscopic stool-sample evaluation. Epidemiological and clinical data were recorded.
Out of 813 migrant children screened, 241 (29.6%) presented at least one parasite, and 89 (10.9%) more than one. The median age was 6.6 years (IQR: 3.1-11.9) and 58.9% were males. Most cases were referred for a health exam; only 52.3% of children were symptomatic, but 43.6% had eosinophilia. The most common diagnosis were giardiasis (35.3%), schistosomiasis (19.1%), toxocariasis (15.4%), and strongyloidiasis (9.1%). After the multivariate analysis, African origin and presenting with eosinophilia were the main risk factors for parasitism.
parasitosis are frequent among migrant children. Children are often asymptomatic, and thus active screening for parasitosis should be considered among high-risk populations. Eosinophilia can be useful to guide complimentary tests, as well as geographical origin, but normal eosinophil count does not exclude parasitosis.
全球化推动了过去几十年的人口流动，使输入性疾病成为焦点。由于行为习惯，儿童更容易感染寄生虫病。本研究旨在调查移民儿童寄生虫感染的流行情况及其与寄生虫病相关的因素。
回顾性横断面研究（2014-2018 年），纳入被诊断为寄生虫病的儿童。根据血清学和/或粪便显微镜检查结果进行诊断。记录流行病学和临床数据。
在 813 名筛查的移民儿童中，241 名（29.6%）至少有一种寄生虫，89 名（10.9%）有多种寄生虫。中位年龄为 6.6 岁（IQR：3.1-11.9），58.9%为男性。大多数病例是为体检而来；只有 52.3%的儿童有症状，但 43.6%有嗜酸性粒细胞增多症。最常见的诊断是贾第虫病（35.3%）、血吸虫病（19.1%）、弓蛔虫病（15.4%）和类圆线虫病（9.1%）。多因素分析后，非洲裔和伴有嗜酸性粒细胞增多症是寄生虫感染的主要危险因素。
寄生虫病在移民儿童中很常见。儿童通常无症状，因此应考虑对高危人群进行寄生虫病的主动筛查。嗜酸性粒细胞增多症可用于指导补充检查，以及地理来源，但嗜酸性粒细胞计数正常并不能排除寄生虫病。
