世界卫生组织近日公布了2018年可致大规模爆发的八种严重疾病，其中包括一种称为“X疾病”的神秘致命病原体，并可从多种源头形成及随时爆发。世卫形容“X疾病”属于已知的不知名疾病。

Scientists from the World Health Organization (WHO) say the world is possibly at risk from a deadly disease. However, they do not know its name or what it does and looks like.

世界卫生组织的科学家说，世界可能面临着致命疾病的危险。但是，他们不知道它的名字，也不知道它是什么样子。

They have called it “Disease X”. It could be caused by a virus(病毒). The WHO said Disease X could go unnoticed until it is too late and it is quickly spreading around the world. The WHO is taking the threat of Disease X seriously. It is putting a lot of money into research and is preparing a plan for a sudden outbreak.

他们称它为“X疾病”。它可能是由一种病毒引起的。世卫组织表示，X疾病可能会被忽视，直到为时已晚，而且它正在迅速蔓延整个世界。世卫组织正在认真对待X病的威胁。它正在为研究投入大量资金，并正在为一次突然爆发做准备。

The scientists said that Disease X could come from many different sources. It could come from existing diseases changing; it could come from terrorism and bio-weapons; it could also come from scientists using DNA-changing technology to make entirely new viruses. The biggest threat could come from animals. The U.S. Centers for Disease Control and Prevention said, "Scientists estimate that more than 6 out of every 10 known infectious diseases in people are spread from animals." Everyone living closer together in cities and increasing international travel and tourism will make it easier for diseases to spread.

科学家们说，X病可能来自许多不同的来源。它可能来自于现有的疾病变化；它可能来自恐怖主义和生物武器，也可能来自科学家利用DNA改变技术制造全新病毒。最大的威胁可能来自动物。美国疾病控制和公共卫生中心的科学家们说：“每10个已知的人类传染病中，就有超过6个是从动物身上传播的。”人们在城市中越来越挤的生活以及国际旅游和旅游业的增加将使疾病更容易传播。
