（北京9日综合电）新加坡“杜克-NUS医学院”(Duke-NUS Medical School)和中国的研究人员在蝙蝠身上发现一种新的“丝状病毒”(filovirus)。这种传染性病毒会让感染的人严重出血。上述研究指出：这种病毒是在中国的“食果类蝙蝠”(fruit bats)身上被发现。它类似致命的“马堡病毒”(Marburg Virus)和伊波拉病毒(Ebola viruses)，后两者曾是肆虐非洲部分地区的出血性病毒。

“丝状病毒”(特别是伊波拉和马堡病毒)能够透过感染人类器官及破坏血管，造成感染者严重发烧以及致命性的出血。 这种病毒因为在中国云南省的勐腊被发现，因此又被称为“勐腊病毒”，它已构成物种间传染的潜在风险。

“杜克-NUS医学院”传染病研究主任王林发(译音，Wang Lin-Fa)教授说，识别出这种病毒，有助于预防伊波拉式的疫情大爆发。

他说：“研究蝙蝠传播丝状病毒的遗传多样性和地理分布，对于风险评估和预防疫情非常重要。因为这类传染病可以在毫无预警的情况下影响大众，造成破坏性的病毒。” 王林发说，分析显示，勐腊病毒在演化上跟伊波拉和马堡病毒有密切关系。
