8月7日,这项由意大利米兰大学生物医学科学系研究者主导的研究在线发表于《柳叶刀》预印本网站上(该论文已经投稿《柳叶刀》杂志,尚未经同行评议和接收)。“我们的研究提供了强有力的证据证明:2019年夏末,新冠病毒已经在意大利北部传播。”论文中写到,与武汉发现的早期毒株相比,这种毒株存在非常明显的不同! 米兰大学的这个实验室是世卫组织认证的麻疹和风疹监测机构,他们凭借着过往的经验觉察到,有一种不知名的原因导致了人们看起来患了麻疹,但到真的诊断时,却又发现不是。 那么,不知名的原因是什么呢?研究人员决定开始在遗弃样本中找答案。 样本包括口咽拭子、尿液和血清,全部保存在米兰大学生物实验室的零下80°C的样本库中。 他们研究了来自156个病例的共计435个口咽拭子、尿液和血清样本,核酸检测结果显示,发现13个病例存在新冠病毒感染的分子证据。其中11个病例的样本采集于2019年8月至2020年2月期间,2个病例的样本采集于2020年3月至2021年3月期间,9例都是2019年采样。 论文截图  论文中记录了更惊人的细节:第一个新冠病毒RNA检测呈阳性的样本是早在2019年9月12日采集的尿
