Abstract
To investigate the possibility of earlier cases of severe acute respiratory syndrome coronavirus 2 infection than previously recognized, we retrospectively tested pooled samples from 1,700 persons with respiratory signs/symptoms seen at Stanford Health Care, Palo Alto, California, USA, during the last 2 months of 2019. We found no evidence of earlier infection.
摘要
为了探究 2019 年 12 月美国加利福尼亚州斯坦福健康医疗中心出现呼吸道症状/体征的 1700 例患者中是否存在比先前认知更早的严重急性呼吸综合征冠状病毒 2 型感染病例，我们对其最后 2 个月的呼吸道症状/体征患者的混合样本进行了回顾性检测。我们并未发现更早感染的证据。
