To determine the epidemiologic and clinical characteristics of patients in Spain with imported arbovirus infections, we analyzed 22,655 records from a collaborative network for January 2009–December 2018. Among 861 arbovirus infections, 845 were monoinfections (456 [53%] dengue, 280 [32.5%] chikungunya, 109 [12.7%] Zika) and 16 (1.8%) were co-infections. Most patients were travelers (56.3%) or immigrants returning to Spain after visiting friends or relatives (31.3%). Median patient age was 37 years; most (62.3%) were women and some (28.6%) had received pretravel advice. Only 12 patients were immunosuppressed. Six cases (all dengue monoinfections, none in immunosuppressed patients) were severe. Since 2014, nondengue arbovirus infections increased; until 2016, chikungunya and Zika were most common. Imported arbovirus infections (mostly dengue) were frequently diagnosed, although increased chikungunya and Zika virus infections coincided with their introduction and spread in the Americas. A large proportion of cases occurred in women of childbearing age, some despite receipt of pretravel advice.

为了确定西班牙患有进口虫媒病毒感染的患者的流行病学和临床特征，我们分析了来自协作网络的2009年1月至2018年12月的22655条记录。在861次虫媒病毒感染中，有845例是单次感染（456 [53％]登革热，280 [32.5] ％]是基孔肯雅热，109 [12.7％] Zika）和16（1.8％）是共同感染。大多数患者是旅行者（56.3％）或在拜访亲友后返回西班牙的移民（31.3％）。患者中位年龄为37岁；大多数（62.3％）是女性，一些（28.6％）已接受旅行前建议。仅12例患者被免疫抑制。六例（所有登革热单次感染，免疫抑制患者无一例）严重。自2014年以来，非登革热虫媒病毒感染有所增加；直到2016年，基孔肯雅热和寨卡最常见。尽管基孔肯雅热和寨卡病毒感染的增加与它们在美洲的传入和传播相吻合，但经常诊断出输入虫媒病毒感染（多数是登革热）。很大一部分病例发生在育龄妇女中，有些病例尽管接受了旅行前的建议。
