Abstract

A large number of coronavirus disease 2019 (COVID-19) patients have been cured and discharged due to timely and effective treatments. While some discharged patients have been found re-positive nucleic acid again in the recovery phase. Until now, there is still a great challenge to its infectivity and the specific potential mechanism which needs further discussion. However, more intensive attention should be paid to the prognosis of recovered patients. In this review, we mainly focus on the characteristics, potential reasons, infectivity, and outcomes of re-detectable positive patients, thereby providing some novel insights into the cognition of COVID-19.

摘要

大量的 2019 冠状病毒病(COVID-19)患者由于及时和有效的治疗而痊愈并出院。然而,一些出院患者在恢复期再次被发现核酸检测呈阳性。到目前为止,其传染性和特定的潜在机制仍然是一个巨大的挑战,需要进一步讨论。然而,应该更加关注康复患者的预后。在这篇综述中,我们主要关注再次检测呈阳性患者的特征、潜在原因、传染性和结局,从而为 COVID-19 的认知提供一些新的见解。
