路透社:意大利研究显示,新冠病毒去年9月就已在意大利流传(双语)
锡耶纳大学为同一项研究课题:“意大利大流行病前SARS-CoV-2抗体的意外检测”的研究中,又进行了一项具体的SARS-CoV-2抗体检测。
It showed that four cases dated back to the first week of October were also positive for antibodies neutralizing the virus, meaning they had got infected in September, Giovanni Apolone, a co-author of the study, told Reuters.
