@CivisRomanvsSum @mattyglesias Fully asymptomatic isn't really that common, most get symptoms (99% with Omicron in Norway report, 75% over entire pandemic according to CDC), and if asymptomatic, probably no symptoms YET, and often highly contagious.
@CivisRomanvsSum@mattyglesias完全无症状并不常见，大多数人都会出现症状（挪威的奥米克罗报告中有99%的人出现症状，根据疾病预防控制中心的数据，整个大流行期间有75%的人出现症状），如果没有症状，可能还没有症状，而且通常具有高度传染性。
