In Spain, 12% of the population are immigrants. The impact of immigration in Spain on cystic echinococcosis (CE) is unknown. The aim of this study was to describe the epidemiology of CE in immigrants in western Spain.
First, a retrospective descriptive study of patients diagnosed with CE in the University Hospital of Salamanca (CAUSA) between January 1998 and December 2014 was designed. Second, we studied the seroprevalence of CE in sera from foreigners who received treatment in the Tropical Medicine Unit.
A total of 550 patients with new CE-related diagnoses were registered; of these, 16 (2.9%) were immigrants, of whom 10 (63%) were male. The age (mean±SD) was 34.6±12.8 years. The incidence rate of CE in immigrants was 8.76 cases per 105 person-years. Eight (50%) cases presented asymptomatically. Seroprevalence of CE in foreign patients was 2.3%. It was higher in North African population (4.2%), followed by sub-Saharan (2.4%) and Latin American (1.8%) (p=0.592) populations. The seroprevalence was higher in those who arrived recently (<12 months) vs those who arrived earlier (≥12 months), 3.5% vs 1.3% (p=0.077).
The epidemiological and clinical characteristics of CE in immigrants are different than those of the native population, and their influence on CE burden in our endemic area is still limited.
在西班牙，有 12%的人口为移民。移民对西班牙包虫病（CE）的影响尚不清楚。本研究旨在描述西班牙西部移民中 CE 的流行情况。
首先，我们设计了一项对 1998 年 1 月至 2014 年 12 月期间在萨拉曼卡大学医院（CAUSA）诊断为 CE 的患者进行的回顾性描述性研究。其次，我们研究了在热带医学科接受治疗的外国人血清中 CE 的血清流行率。
共登记了 550 例新的与 CE 相关的诊断病例，其中 16 例（2.9%）为移民，其中 10 例（63%）为男性。年龄（平均值±标准差）为 34.6±12.8 岁。移民中 CE 的发病率为 8.76 例/105 人年。8 例（50%）患者无症状。外国患者的 CE 血清流行率为 2.3%。北非人群（4.2%）较高，其次是撒哈拉以南地区（2.4%）和拉丁美洲（1.8%）（p=0.592）。最近（<12 个月）到达的人群的血清流行率（3.5%）高于更早到达的人群（1.3%）（p=0.077）。
移民中 CE 的流行病学和临床特征与本地人群不同，他们对我们流行地区 CE 负担的影响仍然有限。
