新华社北京2月6日电随着来自中国的新型冠状病毒持续扩散，一些人担心这种病毒可能潜伏在从中国运来的包裹表面。你有可能经包裹感染新型冠状病毒吗？答案很简单：可能性很小。

　　据英国《每日邮报》网站2月3日报道，美国联邦卫生机构和传染病专家都说，这种病毒在邮寄包裹上存活不了多久，人际传播比从物体表面感染的可能性要大得多。

　　美国疾病控制和预防中心(CDC)在其网站上解释说，经物体表面感染冠状病毒的可能性微乎其微。

　　虽然一个人可以携带病毒数天、甚至数周，但病毒不会在体外存活很长时间。

　　美国CDC说，这意味着，如果在物体表面发现病毒，其寿命只有“几个小时”。

　　而且，包裹在送达之前要经历不同的环境，这让病毒存活的可能性更小。

　　此外，美国宾夕法尼亚州立大学传染病动力学中心主任伊丽莎白·麦格劳说，纸箱不是病毒滋生的好场所。

　　她对美国全国公共广播电台记者说：“据我们对这些病毒的了解，它们在物体表面不会长时间生存，尤其是多孔表面，比如硬纸板。”

　　此外，美国境内外目前还没有任何一起已知病例是因为处理包裹染病的。

　　CDC网站说，从中国运来的产品或包装传播病毒的风险非常低。

　　该机构说，最应担心的是“呼吸道飞沫”，当感染者咳嗽或打喷嚏时，它们便会传播开来。

　　卫生专家建议采取预防措施，比如用温水和肥皂洗手，咳嗽或打喷嚏时用肘窝而不是手去遮挡，以防止病毒传播。

Q: Am I at risk for novel coronavirus from a package or products shipping from China?

There is still a lot that is unknown about the newly emerged 2019 novel coronavirus (2019-nCoV) and how it spreads. Two other coronaviruses have emerged previously to cause severe illness in people (MERS and SARS). 2019-nCoV is more genetically related to SARS than MERS, but both are betacoronaviruses with their origins in bats. While we don’t know for sure that this virus will behave the same way as SARS and MERS, we can use the information from both of these earlier coronaviruses to guide us. In general, because of poor survivability of these coronaviruses on surfaces, there is likely very low risk of spread from products or packaging that are shipped over a period of days or weeks at ambient temperatures. Coronaviruses are generally thought to be spread most often by respiratory droplets. Currently there is no evidence to support transmission of 2019-nCoV associated with imported goods and there have not been any cases of 2019-nCoV in the United States associated with imported goods. Information will be provided on the 2019 Novel Coronavirus website as it becomes available.
