@Nutmeg031992 @MichaelColey @trvrb "Cold-like symptoms" is by definition symptomatic. I have no idea if CDC is using polls or what other sources. Usually if you dig into their work you can find sources, but I'm not motivated to bother because my confidence in them is so low anyway.
@肉豆蔻031992@MichaelColey@trvrb“感冒样症状”定义为有症状。我不知道CDC是否使用民意调查或其他来源。通常，如果你深入他们的工作，你可以找到来源，但我没有动力去打扰他们，因为我对他们的信心太低了。
