BRIEF REPORT
Positive virus detection in patients who recovered from COVID-19 during quarantine period between discharge and home: a two-center experience in Wuhan, China Xiaobing Wang 1,2 & Ping Zhang 3 & Jun Xiao 1,2 & Yue Zhu 1,2 & Lin Zhang 4 & Liping Chen 1,2 Received: 13 April 2020 / Accepted: 28 April 2020 # Springer-Verlag GmbH Germany, part of Springer Nature 2020
Abstract The incidence of re-positive virus detection in patients who recovered from COVID-19 during quarantine was 6.2% in two designated locations, in Wuhan, indicating that suggestions for patients after discharge to be quarantined before leaving for home might be necessary. This experience might be referred to by other countries with epidemic outbreak. Keywords Re-positive virus detection . COVID-19 . Quarantine period . After discharge . Two-center experience . Wuhan
Introduction As of April 8, 2020, the COVID-19 epidemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) had spread all over China and more than 200 other countries and areas, with 1,356,780 confirmed cases and 79,385 deaths [1]. Although the COVID-19 epidemic has been under preliminary control in China, little is known about SARSCoV-2. In Wuhan, China, patients who recovered from COVID-19 before February 22, 2020, were required to be quarantined at home after discharge from hospital. However, some native news and case reports reported positive virus detections in recovered patients [2, 3]. In view of the potential Xiaobing Wang, Ping Zhang and Jun Xiao contributed equally to this work. * Lin Zhang [email protected] * Liping Chen [email protected] 1

risk of virus transmission for those recovered patients with repositive virus detection, the local government suggested recovered patients after discharge to designated locations (usually hotels), to be quarantined for another 14 days at least and receiving SARS-CoV-2 nucleic acid real-time reverse transcription polymerase chain reaction (RT-PCR) tests during quarantine for free. This study aims to investigate the incidence of positive virus detection in patients who recovered from COVID-19 during quarantine period between discharge and home based on a population in two designated locations in Wuhan, China, and describe the baseline characteristics of these patients.
Methods Study design and patients Patients who recovered from COVID-19 were discharged from different designated hospitals in Wuhan, and came to Qitian Hotel (location 1) and Yagangju Hotel (location 2) to be quarantined before leaving for home. Appointed commun
