The SARS-CoV-2 pandemic is underway and millions of people have been infected. A large number of patients with COVID-19 have recovered and been discharged. While a number of recovered patients test positive again or even have a recurrence of clinical symptoms. Some researchers believe that a positive retest is related to the long-term persistence of the virus in the body, although there is some evidence in favor of reinfection. In this study, we focus more on the possible reasons for positive retesting, antibody responses, and review of possible reinfection case reports.
严重急性呼吸综合征冠状病毒2（SARS-CoV-2）大流行正在进行，数百万人已被感染。大量冠状病毒病（COVID-19）患者已康复并出院。然而，一些康复患者再次检测呈阳性，甚至出现临床症状复发。一些研究人员认为，再次检测呈阳性与病毒在体内长期持续存在有关，尽管有一些证据支持再次感染。在本研究中，我们更关注再次检测呈阳性的可能原因、抗体反应，并回顾可能的再次感染病例报告。
