Factors associated with prolonged duration of viral clearance in non-severe SARS-CoV-2 patients in Osaka, Japan.

Background: We investigated factors associated with prolonged viral clearance of SARS-CoV-2 among non-severe adult patients in Osaka, Japan. A total of 706 laboratory-confirmed COVID-19 patients were enrolled in this longitudinal observational study between 29 January 2020 and 31 May 2020, across 62 hospitals and three non-hospital recuperation facilities.

Methods: Logistic regression analysis was performed to investigate the factors associated with prolonged (29 days: upper 25% in duration) viral clearance of SARS-CoV-2.

The characteristics and clinical course of patients with COVID-19 who received invasive mechanical ventilation in Osaka, Japan.
