美国顶级传染病专家福奇日前指出，已经发现新冠病毒产生变异的迹象，而且这种变异可能导致该病毒更容易传播，但目前尚不清楚感染这种新变异病原体的人病情是否会更严重。

The coronavirus has mutated in a way that might help the pathogen spread more easily, White House health advisor Dr. Anthony Fauci said Thursday.

白宫卫生顾问安东尼·福奇博士本周四 Research is underway to confirm the possible mutation and its implications, Fauci said, adding that “there’s a little dispute about it.” Viruses naturally mutate and scientists have previously said they have observed minor mutations in the coronavirus that have not impacted its ability to spread or cause disease in any significant way.

福奇称，目前正在进行研究以证实这一可能发生的变异及其潜在影响。他补充道：“关于病毒变异存在一点争议。”病毒会自然地发生变异，科学家先前指出，他们已经观察到新冠病毒发生了一点微小的变异，但没有显著地影响到病毒传播或致病的能力。

The possible mutation that Fauci cited was reported on by investigators at Los Alamos National Laboratory in an article published by the journal Cell earlier Thursday. Virologists at Scripps Research in Florida also wrote about the mutation last month, saying it “enhances viral transmission.” It’s unclear when the mutation might have occurred.
