Polymerase Chain Reaction Assays Reverted to Positive in 25 Discharged Patients With COVID-19

Abstract

We report the observation that 14.5% of COVID-19 patients had positive RT-PCR testing again after discharge. We describe correlations between laboratory parameters and treatment duration (P = .002) and time to virus recrudescence (P = .008), suggesting the need for additional measures to confirm illness resolution in COVID-19 patients.
