Title: Virologic and clinical characteristics for prognosis of severe COVID-19: a retrospective observational study in Wuhan, China Document date: 2020_4_6
ID: 4989atst_14
Snippet: The dynamic pattern of viral shedding showed that most patients had intermittent virus shedding. Intriguingly, two patients had significant clinical improvement, but their viral nucleic-acid tests remained positive for a few days. As of March 17, 2020, the median duration of viral shedding was 31 days (IQR, 27-34 days) after symptom onset, and the longest duration of viral shedding was 57 days ( Figure 1A ). The interval between first and last po.....
Document: The dynamic pattern of viral shedding showed that most patients had intermittent virus shedding. Intriguingly, two patients had significant clinical improvement, but their viral nucleic-acid tests remained positive for a few days. As of March 17, 2020, the median duration of viral shedding was 31 days (IQR, 27-34 days) after symptom onset, and the longest duration of viral shedding was 57 days ( Figure 1A ). The interval between first and last positive PCR assay results (4 to 22 days) was extensively prolonged in patients with poor recovery.
