Present study aimed to estimate the incidence of recurrent SARS-CoV-2 RNA positivity after recovery from COVID-19 and to determine the factors associated with recurrent positivity. We searched the PubMed, MedRxiv, BioRxiv, the Cochrane Library, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry for studies published to June 12, 2020. Studies were reviewed to determine the risk of bias. A random-effects model was used to pool results. Heterogeneity was assessed using I. Fourteen studies of 2568 individuals were included. The incidence of recurrent SARS-CoV-2 positivity was 14.8% (95% confidence interval [CI] 11.44-18.19%). The pooled estimate of the interval from disease onset to recurrence was 35.4 days (95% CI 32.65-38.24 days), and from the last negative to the recurrent positive result was 9.8 days (95% CI 7.31-12.22 days). Patients with younger age and a longer initial illness were more likely to experience recurrent SARS-CoV-2 positivity, while patients with diabetes, severe disease, and a low lymphocyte count were less likely to experience. Present study concluded that the incidence of recurrent SARS-CoV-2 positivity was 14.8% suggesting further studies must be conducted to elucidate the possibility of infectious individuals with prolonged or recurrent RNA positivity.
本研究旨在估计 COVID-19 康复后 SARS-CoV-2 RNA 再次阳性的发生率,并确定与再次阳性相关的因素。我们检索了 PubMed、MedRxiv、BioRxiv、Cochrane 图书馆、ClinicalTrials.gov 和世界卫生组织国际临床试验注册平台,以获取截至 2020 年 6 月 12 日发表的研究。对研究进行了回顾以确定偏倚风险。使用随机效应模型对结果进行汇总。使用 I 评估异质性。纳入了 14 项研究共 2568 人。SARS-CoV-2 再次阳性的发生率为 14.8%(95%置信区间 11.44-18.19%)。疾病发作到复发的间隔时间的汇总估计值为 35.4 天(95%置信区间 32.65-38.24 天),从最后一次阴性到再次阳性的间隔时间为 9.8 天(95%置信区间 7.31-12.22 天)。年龄较小和初始疾病持续时间较长的患者更有可能出现 SARS-CoV-2 再次阳性,而患有糖尿病、严重疾病和淋巴细胞计数较低的患者则不太可能出现。本研究的结论是,SARS-CoV-2 再次阳性的发生率为 14.8%,这表明必须进一步开展研究以阐明具有持续或反复 RNA 阳性的传染性个体的可能性。
