@i_petersen @MichaelSFuhrer @VGrubsky @AndrewHayen The population survey was a good way to get data on ascertainment rate. I'm less convinced about symptomality. And generally not sure how to apply any of that to people who now do or don't think they had covid.
@i_petersen @MichaelSFuhrer @VGrubsky @AndrewHayen 人口调查是获取确定率数据的好方法。我不太相信症状。而且通常不知道如何将其中任何一种应用于现在或不认为自己患有 covid 的人。
