针对这次肺炎疫情影响到外贸生意问题，以及客户申请退款或者咨询产品是否携带病毒问题。

我们如何较好的委婉回复客户呢？

At present, the Chinese government is taking the most powerful measures，and everything is under control. Life is normal in most other parts of China by far, with only a few cities like Wuhan affected. I believe it will all return to normal soon.  Thanks!

或者：

The main epidemic situation is only in Wuhan,which is under control.The government is actively taking many measures to deal with it. Other cities have little impact.  We believe it will be restored soon.

可以表明国家已经积极采取有力的措施，战胜疫情。很快会恢复正常。

尽量不要让客户觉得疫情严重，引起恐慌。什么很多人出不了门，经济下滑，生意惨淡尽量不要涉及最好。

往好的方面去引导和回复客户。

不恐慌，相信国家！能度过这个难关！

武汉加油！中国加油！
