We recently reported a patient with coronavirus disease 2019 reinfection. Here, we show that serum neutralizing antibodies could be detected during the first episode but not at the presentation of the second episode. During reinfection, neutralizing antibodies and high avidity immunoglobulin G were found within 8 days after hospitalization, whereas immunoglobulin M response was absent.
我们最近报告了一例2019冠状病毒病再次感染的患者。在此,我们表明在首次发病期间可检测到血清中和抗体,但在第二次发病时未检测到。在再次感染期间,住院后8天内发现了中和抗体和高亲和力免疫球蛋白G,而未出现免疫球蛋白M反应。
