The discharged patient had to conform to the following conditions 6 : (1) The patient' temperature returned to normal for more than three days; (2) respiratory symptoms improved significantly; lung imaging showed a significant improvement in acute exudative lesions; (3) the RT-PCR test of pharyngeal swab samples had two consecutive negative results (at least 24 hours apart), and we recorded the earliest date the nucleic acid test turned negative. The days until the symptoms disappeared in patients with COVID-19 were positively correlated with the history of epidemiology (imported cases),the days needed for the pharyngeal swab nucleic acid test to turn negative, and the days of hospitalization.	./cache/cord-340051-r9kn34wd.txt	./txt/cord-340051-r9kn34wd.txt
