@FinchTH @exsibilation There wasn't a shortage for LONG time before CDC changed the guidance, and even then it was half hearted, confusing, and really poorly implemented (e.g. hospitals making people switch to surgical).
All the rest you said true of course.
@FinchTH @exsibilation 在 CDC 更改指南之前很长一段时间都没有短缺，即便如此，它还是三心二意，令人困惑，而且实施得很差（例如，医院让人们改用外科手术）。
你说的其他所有内容当然都是真的。
