主帖说美国和意大利在“2019年9月10月的血液样本中就有新冠抗体”。

俺搜了一下路透的报道。

“意大利在2019年9月到2020年3月之间抽取了959位健康人的血样用于癌症检测。在2020年11月重新检测时发现,11.6%的血样有新冠抗体(Their findings released in November showed 11.6% of 959 healthy volunteers enrolled in the cancer screening trial between September 2019 and March 2020 had signs of having already encountered SARS-CoV-2, most of them well before February)”。

但是荷兰伊拉斯姆斯大学的学者说:“根据我们定的标准,不能确定大部分这些阳性报告,因此,我们有不同的结果”("Based on the criteria that we set, we could not confirm the majority of positives. Therefore, we had a different conclusion," said Marion Koopmans at Erasmus University)

荷兰伊拉斯姆斯大学的标准要求在三方面(IgM,IgC和抗体中性化)都必须检测,而结果是全部非阳性(
But Erasmus' criteria required all three coronavirus-linked antibodies - IgM, neutralising antibodies and IgG - to be identified, and none of the samples fulfilled that requirement)。
