中外科学家都发现一定比例新冠痊愈病人核酸检测结果阴性后，会再次检测阳性。不排除这些复阳者还有可能有复制病毒并有传染性。 意大利跟踪176例痊愈患者，发现18%复阳，少部分也许有传染性。 国内医学专家观点是可能有消化道新冠病毒还未彻底清除，鼻腔咽部呼吸道采样阴性不能证明彻底清除了病毒，所以国内加测肛拭子。 大批回国人员，跟据这个比例，出现隔离期后复阳很正常。 说明防疫工作的困难性，一定要做好监测随访。 JAMA原文： November 12, 2020 Assessment of SARS-CoV-2 RNA Test Results Among Patients Who Recovered From COVID-19 With Prior Negative Results ; ; ; et al ; ; ; Author Affiliations Article Information JAMA Intern Med.
