@i_petersen @MichaelSFuhrer @VGrubsky @AndrewHayen I do think that in 2020 when there was limited access to testing, no LFTs, etc., and less awareness of the full range of symptoms. a LOT of people had covid with milder symptoms and were never diagnosed and don't consider themselves to have covid. Later, less so.
@i_petersen @MichaelSFuhrer @VGrubsky @AndrewHayen 我确实认为在 2020 年进行测试的机会有限，没有 LFT 等，并且对所有症状的认识也较少。很多人感染了症状较轻的新冠病毒，但从未被诊断出来，也不认为自己感染了新冠病毒。后来就少了。
