我们评估了居住在意大利洛迪红区的献血者（BD）的SARS-CoV-2 RNA和中和抗体。在2020年2月20日之后招募的390名BD中，当伦巴第发现首例COVID-19病例时，91名（23%）年龄在19-70岁之间的人抗体呈阳性。在另外17个（4.3%）BD中检测到病毒RNA，约28%（108/390）有病毒暴露证据。早在2月12日采集的5个储存样本血清反应呈阳性。
We evaluated SARS-CoV-2 RNA and neutralising antibodies in blood donors (BD) residing in the Lodi Red Zone, Italy. Of 390 BDs recruited after 20 February 2020 - when the first COVID-19 case in Lombardy was identified, 91 (23%) aged 19-70 years were antibody positive. Viral RNA was detected in an additional 17 (4.3%) BDs, yielding ca 28% (108/390) with evidence of virus exposure. Five stored samples collected as early as 12 February were seropositive.
