本周第二條報導,原文鏈接:http://www.sciencemag.org/content/338/6111/1132.1.full.pdf Madeira, Portugal 2 Dengue Outbreak Strikes European Outpost 登革熱在歐洲前哨突然大爆發(fā) 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. 登革熱突然在位于摩洛哥以西700公里的葡(萄牙)屬馬德拉島爆發(fā),自從10月3號以來已有1300多人患病。位于Stockholm的歐洲疾病防控中心上周說,登革熱一般不足以致命,但是會造成肌肉組織嚴重受損和關節(jié)疼痛。它發(fā)生于很多熱帶和亞熱帶國家,然而從上世紀20年代之后就再也沒有在歐洲出現(xiàn)過。目前還沒有發(fā)現(xiàn)死亡病例,但仍然有89名患者需要住院治療。 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是瑞士蘇黎世大學的一名寄生生物學家,他說登革熱病毒可以通過蚊子傳播,其中 Aedes aegypti蚊子是最有效的傳播媒介。這種蚊子2004年入侵馬德拉島,并開始傳播登革熱病毒。政府開始曾試圖控制蚊子,“但是并未奏效然后就停止了”。Schaffner進一步警告說,A. aegypti蚊子并沒有出現(xiàn)在在歐洲大陸,但是它的近親A. albopictus,也叫做亞洲老虎蚊子,已經(jīng)在大部分的地中海國家安營扎寨。雖然這種蚊子的傳播效率低一些,但是今年夏天依然可能會是一種傳播媒介(來傳播登革熱病毒)。 *************************************************************** Science的原文和本翻譯僅用于網(wǎng)友交流學習之用,若您有其它用途,比如商業(yè)用途等,請聯(lián)系Science雜志社了解原文使用權等相關事宜。謝謝!
