As Georgetown international health law professor Alexandra Phelan pointed out on Twitter, there's no formal law or process for declaring a pandemic over.

就像乔治城大学国际卫生法律教授 Alexandra Phelan 在推特上指出的，现在没有成文法律或路径来宣布疫情结束。

What can be good or bad is the way human beings create and share that technology and the rules — the formal laws and institutions and the informal assumptions and practices — that we use around that technology.

好坏取决于人类创造和分享技术的方式以及我们围绕该技术使用的规则——正式的法律和制度以及非正式的假设和实践。
