Thus, we suggested that the patient should be negative for at least 3 consecutive nucleic acid tests before discharge, and the test time should be no earlier than the 23rd day since the onset of the disease. According to the latest COVID-19 clinical diagnosis and treatment guideline [3] , patients who meet the following four criteria can be discharged: (1) the body temperature has returned to normal for more than 3 days; (2) the respiratory symptoms have improved significantly; (3) the pulmonary imaging examination shows that the acute exudative lesions have improved significantly, (4) two consecutive negative nucleic acid test for respiratory specimens such as sputum and nasopharyngeal swabs (sampling interval at least 24 hours). The median time from the onset of COVID-19 to the occurrence of two consecutive negative nucleic acid tests in 845 patients with COVID-19 was 21 days (range: 1-56 days).	./cache/cord-289873-6hivjqof.txt	./txt/cord-289873-6hivjqof.txt
