@DrTomFrieden Everyone circulating in public is exposed to covid.
If you've been home alone for the past two weeks, yeah you're not a putting the cancer patient next to you in the pharmacy, at a workplace, on transit, etc. at risk.
Everyone else, mask up.
@Tomfrieden博士每个在公共场合传播的人都会接触到新冠病毒。
如果你在过去两周里一直独自在家，是的，你不会让你旁边的癌症患者在药房、工作场所、运输途中等处于危险之中。
其他人都要伪装起来。
