@RidleyDM @DrLeanaWen I mean it doesn't have to be masks, there are other measures to do the same thing, and the moderate ones (short of broad closures) usually poll fine too. They're usually perceived as more costly, and probably are (but that's somewhat subjective I suppose).
@RidleyDM@DrLeanaWen我的意思是，不一定要戴口罩，还有其他措施可以做同样的事情，而温和的措施（不包括大范围的关闭）通常也很好。他们通常被认为成本更高，而且很可能是（但我认为这有点主观）。
