@BillHanage Individual frame:
Avoid exposure as well as you can for as long as possible until more evidence arrives. But it's really situation dependent. Many people can make reasonable choices to reduce exposure that they aren't making. Some can't.

尽可能长时间避免接触，直到有更多证据。但这确实取决于具体情况。许多人可以做出合理的选择来减少他们没有做的暴露。有些人不能。
