研究：英国新冠疫情或存在1300多个不同源头

然后，就像一个巨大版本的亲子鉴定一样，遗传学家试图拼凑出病毒庞大的族谱。

This was combined with data on international travel to get to the origins of the UK epidemic.

这一数据与国际旅行数据相结合，得出了英国疫情的起源。

They found the UK's coronavirus epidemic did not have one origin - but at least 1,356 origins. On each of those occasions somebody brought the infection into the UK from abroad and the virus began to spread as a result.

他们发现，英国的新冠疫情不只有一个源头，而是至少有1356个源头。每次有境外输入病例时，就会把病毒从国外带到英国，之后病毒开始传播。

"The surprising and exciting conclusion is that we found the UK epidemic has resulted from a very large number of separate importations," said Prof Nick Loman, from Cog-UK and the University of Birmingham.

来自该机构和伯明翰大学的尼克·洛曼教授说：“令人惊讶和兴奋的结论是，我们发现英国的疫情是由大量单独的外国输入病例造成的。”

"It wasn't a patient zero," he added.

“而不是由一位‘零号病人’引发”，他补充说。

The study showed that less than 0.1% of those imported cases came directly from China. Instead the UK's coronavirus epidemic was largely initiated by travel from Italy in late February, Spain in early-to-mid-March and then France in mid-to-late-March.
