With up to 100 million cases annually, dengue fever is today's most important arboviral disease. Dengue fever is endemic in many parts of South-East Asia, the Indian subcontinent, Oceania and the Americas. The disease mainly affects the local population, but occasionally also visitors from non-endemic areas. In this article we present epidemiological and clinical data on all 26 cases with serological confirmed dengue fever diagnosed in Norway in 1991-1996. 21 patients (81%) were infected in Asia. Typical exanthema, leucopenia, and thrombocytopenia were seen in 71%, 79% and 84% of the cases, respectively. A 37-year-old Indian-born woman developed dengue haemorrhagic fever grade 1 after a visit to New Delhi, while the remaining 25 patients had classical dengue fever. Postinfectious complications were common, and four weeks after the acute illness, hair loss, mental depression and asthenia were reported by 45%, 50% and 100% of the cases, respectively.
登革热每年发病多达1亿例，是当今最重要的虫媒病毒病。登革热在东南亚、印度次大陆、大洋洲和美洲的许多地区呈地方性流行。该病主要影响当地人口，但非流行地区的来访者偶尔也会感染。在本文中，我们呈现了1991年至1996年在挪威确诊的26例血清学确诊登革热病例的流行病学和临床数据。21名患者（81%）在亚洲感染。分别有71%、79%和84%的病例出现典型皮疹、白细胞减少和血小板减少。一名37岁出生于印度的女性在访问新德里后患上了1级登革出血热，其余25名患者患有典型登革热。感染后并发症很常见，急性病四周后，分别有45%、50%和100%的病例报告有脱发、精神抑郁和乏力。
