Dengue Outbreak Strikes European Outpost
登革热在欧洲前哨突然大爆发

An outbreak of dengue fever on the Portuguese island of Madeira, some 700 kilo meters west of Morocco, has sickened more than 1300 people since 3 October. Dengue—which does not usually kill but causes crippling muscle and joint pains—occurs in many tropical and subtropical countries, but Europe has not seen sustained transmission since the 1920s, the European Centre for Disease Prevention and Control in Stockholm said last week. No deaths have been recorded, but 89 patients had to be hospitalized.

登革热突然在位于摩洛哥以西700公里的葡（萄牙）属马德拉岛爆发，自从10月3号以来已有1300多人患病。位于Stockholm的欧洲疾病防控中心上周说，登革热一般不足以致命，但是会造成肌肉组织严重受损和关节疼痛。它发生于很多热带和亚热带国家，然而从上世纪20年代之后就再也没有在欧洲出现过。目前还没有发现死亡病例，但仍然有89名患者需要住院治疗。

The dengue virus can be transmitted by several mosquito species; Aedes aegypti, the most effective vector, invaded Madeira in 2004 and has been spreading since, says Francis Schaffner, a parasitologist at the University of Zurich in Switzerland. Authorities initially tried to control the insects, “but it didn’t work and they stopped,” he says. A. aegypti does not occur in mainland Europe, but its cousin, A. albopictus—better known as the Asian tiger mosquito—is established in most Mediterranean countries and could act as a vector, albeit a weaker one, in the summer, Schaffner warns.

Francis Schaffner是瑞士苏黎世大学的一名寄生生物学家，他说登革热病毒可以通过蚊子传播，其中 Aedes aegypti蚊子是最有效的传播媒介。这种蚊子2004年入侵马德拉岛，并开始传播登革热病毒。政府开始曾试图控制蚊子，“但是并未奏效然后就停止了”。Schaffner进一步警告说，A. aegypti蚊子并没有出现在在欧洲大陆，但是它的近亲A. albopictus，也叫做亚洲老虎蚊子，已经在大部分的地中海国家安营扎寨。虽然这种蚊子的传播效率低一些，但是今年夏天依然可能会是一种传播媒介（来传播登革热病毒）。
