科学家发现埃博拉疫情源头：蝙蝠叮咬2岁男孩
<p>据英国《每日邮报》报道，一个由多国科学家组成的研究团队宣称找到此次埃博拉病毒大爆发的源头：一名2岁男孩被感染该病毒的果蝠叮咬。</p><p>研究人员认为，一名2岁小男孩被感染了埃博拉病毒的果蝠叮咬，随后他又将病毒传给母亲，母子二人都在一周内死亡。此后，埃博拉病毒随着前来参加葬礼的人越传越远，疫情范围越来越大。很早以前，科学家们就已经发现，蝙蝠是埃博拉病毒的主要携带源，但很少传染给人。</p><p>此前，埃博拉病毒爆发多是因为猎人捡到感染病毒动物的肉，并将其卖掉引发的。而在西非乡村地区，果蝠是一种常见食物，经常被熏烤或做汤吃掉。</p><p>但科学家们称，他们还没有百分之百的证据，只能说果蝠是导致此次埃博拉病毒大爆发的可能原因。如果蝙蝠理论获得证实，当地人可能会试图消灭这种动物，这将造成“生态灾难”，因为蝙蝠能给作物授粉和消灭害虫。</p><p><span word="The">The</span> <span word="largest">largest</span> <span word="outbreak">outbreak</span> <span word="of">of</span> <span word="the">the</span> <span word="deadly">deadly</span> <span word="disease">disease</span> <span word="Ebola">Ebola</span> <span word="was">was</span> <span word="caused">caused</span> <span word="by">by</span> <span word="an">an</span> <span word="infected">infected</span> <span word="bat">bat</span> <span word="biting">biting</span> <span word="a">a</span> <span word="toddler">toddler</span>, <span word="say">say</span> <span word="a">a</span> <span word="group">group</span> <span word="of">of</span> <span word="international">international</span> <span word="researchers">researchers</span>.</p><p><span word="The">The</span> 17-<span word="strong">strong</span> <span word="team">team</span> <span word="of">of</span> <span word="European">European</span> <span word="and">and</span> <span word="African">African</span> <span word="tropical">tropical</span> <span word="disease">disease</span> <span word="researchers">researchers</span>, <span word="ecologists">ecologists</span> <span word="and">and</span> <span word="anthropologists">anthropologists</span> <span word="have">have</span> <span word="spent">spent</span> <span word="three">three</span> <span word="weeks">weeks</span> <span word="investigating">investigating</span> <span word="the">the</span> <span word="outbreak">outbreak</span> <span word="of">of</span> <span word="the">the</span> <span word="disease">disease</span> <span word="in">in</span> <span word="Guinea">Guinea</span>, <span word="Liberia">Liberia</span>, <span word="Ivory">Ivory</span> <span word="Coast">Coast</span> <span word="and">and</span> <span word="Nigeria">Nigeria</span>.</p><p><span word="The">The</span> <span word="researchers">researchers</span> <span word="captured">captured</span> <span word="the">the</span> <span word="bats">bats</span> <span word="and">and</span> <span word="other">other</span> <span word="creatures">creatures</span> <span word="near">near</span> <span word="the">the</span> <span word="village">village</span> <span word="of">of</span> <span word="Meliandoua">Meliandoua</span> <span word="in">in</span> <span word="remote">remote</span> <span word="eastern">eastern</span> <span word="Guinea">Guinea</span>, <span word="where">where</span> <span word="the">the</span> <span word="present">present</span> <span word="epidemic">epidemic</span> <span word="began">began</span> <span word="in">in</span> <span word="December">December</span> 2013.</p>
