Category: Article Summary

Topic: Clinical Characteristics and Health Care Setting

• Yuan et al. report that 11% of recovered COVID-19 patients were found to be SARS-CoV-2 RNA positive one or two weeks after hospital discharge, although none were symptomatic at the time of testing. Patients under 18 and patients with shorter hospital stays were more likely to have a positive re-test; no severe cases tested positive after discharge.
