Abstract

Highlights • This study focused on the duration of viral shedding and risk factors in patients with COVID-19 outside of Wuhan, China.• The median duration of viral shedding in the current study was 17 days.• The highest temperature at admission, time from symptoms onset to admission and hospital length of stay were risk factors.

How strong is the evidence?

Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
