新型冠状病毒肺炎(简称"新冠肺炎")患者新型冠状病毒核酸复检阳性(简称"复阳")虽然并未出现再次传染及临床症状加重的情况,但不能排除其潜在风险。分析新冠肺炎复阳现状,总结复阳发生的原因有病毒残留、前期核酸检测呈假阴性,个体免疫功能低下、病毒复燃或再次感染病毒,药物滥用、免疫抑制;基于此,提出"除毒务尽""扶助正气""改善体质"为新冠肺炎恢复期防治复阳的三大原则。

Although re-infection and aggravation of clinical symptoms have not been found in retest virus nucleic acid positive patients with coronavirus disease 2019(COVID-19),the potential risks cannot be ruled out.Therefore,this article was designed to analyze the situation of retest virus nucleic acid positive COVID-19 patients,and to summarize the potential reasons.As a result,virus residual,false-negative result of previous test,weakened individual′s immune function,virus recurrence or re-infection,drug abuse,and immunosuppression were the reasons that may lead to retest positive results.Accordingly,three principles to prevent retest positive in convalescent COVID-19 patients were put forward,which included"to remove the virus thoroughly","to strengthen the vital qi",and"to improve the constitution".
