Among refugees, asylum seekers, or people coming from tropical regions, eosinophilia (>0.5 G/L) is often a sign of parasitic infection, even in the absence of symptoms. The most frequently encountered are helminthiasis such as strongyloidiasis, ancylostomiasis, and schistosomiasis. Management should ideally include screening by three repeated stool analysis and serology. However, collection and storage of stool samples is often difficult in collective accommodation centers. A pragmatic and simplified approach is therefore preferable. Antiparasitic treatment, whether specific or empiric, resolves eosinophilia in most cases. A decision algorithm can guide management, but in doubtful or complex cases, it is advisable to consult a specialist in tropical medicine to further refine the diagnosis and treatment.
在难民、寻求庇护者或来自热带地区的人群中，嗜酸性粒细胞增多（>0.5 G/L）通常是寄生虫感染的迹象，即使没有症状也是如此。最常见的是蠕虫病，如类圆线虫病、钩虫病和血吸虫病。理想的处理方法应包括通过三次重复的粪便分析和血清学进行筛查。然而，在集体收容中心，粪便样本的采集和储存往往很困难。因此，采用务实且简化的方法更为可取。抗寄生虫治疗，无论是特异性的还是经验性的，在大多数情况下都能使嗜酸性粒细胞增多得到缓解。一个决策算法可以指导处理，但在可疑或复杂的病例中，建议咨询热带医学专家以进一步完善诊断和治疗。
