Persistence of positive severe acute respiratory syndrome coronavirus-2 reverse transcription-polymerase chain reaction test result for 24 days in a hospitalized asymptomatic carrier.

An asymptomatic patient diagnosed with SARS-CoV-2 infection remained reverse transcription-polymerase chain reaction-positive for 24 days, although she was quarantined in an isolation hospital. This finding suggests that an asymptomatic patient diagnosed with SARS-CoV-2 infection with abnormal chest computed tomography findings can be an asymptomatic carrier for more than 3 weeks.
