Clinical characteristics of secure acute respiratory syndrome coronavirus 2 reactivation

Topic:

  • Ye at al reviewed clinical and lab records, and chest CT scans for 55 patients with lab-confirmed COVID-19 pneumonia admitted to a hospital in Wuhan, 5 of whom presented with SARS-CoV-2 reactivation after hospital discharge. The time from SARS-CoV-2 negative to positive ranged from 4 to 17 days, suggesting that recovered patients may still be carriers and require an additional round of testing and isolation. 
  • While the results should be interpreted with caution given the small sample size, the findings are important to understand the clinical characteristics and SARS-CoV-2 reactivation potential in COVID-19 patients.
