摘要： 【摘要】 目的  分析北京市输入性罗阿丝虫病患者的临床和流行病学特征。 方法  通过现场流行病学调查，了解病人的活动史、发病就诊过程，临床表现等。 结果  2012~2015年，北京市医疗机构共报告5例临床诊断为罗阿丝虫感染病例，输入地为尼日利亚、喀麦隆、刚果（布）、加蓬。5例患者均有嗜酸性粒细胞增多，其中3例仅有游走性肿块， 1例有眼部症状和皮肤瘙痒，1例有游走性肿块和结膜下虫体移行感。 结论  随着国际交往的日益频繁，势必导致该病输入人数增加。罗阿丝虫病确诊困难，应增强临床医生根据流行病学史和典型症状（游走性肿块和虫体在眼睑或球结膜下移行）诊断病例的意识。

Abstract:

【Abstract】 Objectives  To analyze the clinical and epidemiological characteristic of imported loaiasis in patients in Beijing. Methods  Field epidemiological study was performed pertaining to the patients’ previous activities, sources of infection and treatment as well as clinical pictures. Results  A total of 5 cases of confirmed loaiasis were reported in Beijing from 2011 to 2015. The disease was generally imported from Nigeria, Gameroon, Republic of Congo and Gabon. Increased ratio of eosinophils was seen in the five patients, in whom 3 had simple Calabar swellings, 1 had eye symptoms and skin itching, and another 1 had Calabar swellings and sense of worm migration at the conjunctiva. Conclusion  Imported disease may be increased with more international communication. Loaiasis is hard to diagnose, yet accurate diagnosis of this disease can rely on its characteristic symptoms and epidemiology.
