The treatment and follow-up of 'recurrence' with dischargedCOVID-19 patients: data from Guizhou, China

We reported 20 cases of discharged COVID-19 patients whose RT-PCR test results showed 're-positive'. After finding 're-positive', these patients were admitted to hospital for the second time and were followed up until the end of May 2020. We recorded detailed treatment and follow-up process, and collected relevant data. The possible causes and potential clinical significance of this phenomenon are discussed.
