The dengue viruses (DENV) are endemic in the tropical and sub-tropical countries and cause the most common arthropod-borne viral disease in humans. Travelers visiting endemic areas may both acquire and spread DENV infections, and this is the reason why prevention of mosquito bites is of crucial importance. Dengue fever (DF) has become the most common cause for tropical fever in Swedish tourists. Swedish data from 1995 to 2010 show that the number of DF cases has increased since the beginning of 2000; partly due to improved diagnostics based on IgM detection, and partly due to an increase in the number of tourists traveling to, and between, endemic areas. Young adults aged 20-29 are mostly affected, and epidemiological data indicate increased incidence rates from 2008 onwards. Our data pose a call for attention when traveling to DENV endemic areas as well as an increased awareness among physicians when treating returning travelers.
登革病毒（DENV）在热带和亚热带国家流行，是人类最常见的节肢动物传播的病毒性疾病。前往流行地区的旅行者可能会感染并传播登革病毒，这就是预防蚊虫叮咬至关重要的原因。登革热（DF）已成为瑞典游客热带发热的最常见原因。瑞典1995年至2010年的数据显示，自2000年初以来，登革热病例数有所增加；部分原因是基于IgM检测的诊断方法有所改进，部分原因是前往流行地区以及在流行地区之间旅行的游客数量增加。20至29岁的年轻人受影响最大，流行病学数据表明，自2008年以来发病率有所上升。我们的数据呼吁人们在前往登革病毒流行地区时予以关注，同时也提高医生在治疗归国旅行者时的意识。
