@MichaelSFuhrer I'd ask whether people in close circle are taking precautions. If you live with, work with, go to school with, etc. people not taking precautions, your own precautions, at least if "moderate", are less likely to work.
@MichaelSFuhrer 我想问问圈子里的人是否正在采取预防措施。如果您与不采取预防措施的人一起生活、工作、上学等，那么您自己的预防措施，至少在“适度”的情况下，不太可能起作用。
