This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
After two month of the outbreak of corona virus disease 2019 (COVID-19) in Wuhan China, tens of thousands hospitalized patients, being recovered, little was known about the follow-up of the recovered patients. 758 recovered patients, hospitalized in 17 hospitals previously and quarantined in 32 rehabilitation post stations in Wuhan, China, were retrospectively reviewed for clinical characters, reverse transcriptase- polymerase chain reaction (RT-PCR) from throat swab specimens and serological COVID-19 rapid diagnostic test (RDT) for SARS-Cov-2. Among them, 59 patients (7.78%) had recurrent positive findings for COVID-19 on RT-PCR from throat swabs. Among the 50 patients which was effective samples for antibody detection, 45/50 (90.00%) and 4/50 (8.00%) patients had positive of IgG or dual positive of IgG/IgM RDT for COVID-19, respectively. A certain number of quarantined patients with COVID-19 had recurrent RT-PCR results of SARS-Cov-2, the possibility of transmission in the patients needs further investigation.
