A) Time interval of every two time points among the four time points Negative group: The median time interval between onset of symptom to diagnosis was 6 days (range, − 2 to 17; mean, 6.52) and the median time interval between diagnosis to discharge was 12 days (range, − 1 to 23; mean, 12.50). The median time interval between onset of symptom to discharge was 19 days (range, 5 to 31; mean, 19.01). Positive group: The median time interval between onset of symptom to diagnosis was 5 days (range, 0 to 16; mean, 4.45). a nd the median time interval between diagnosis to discharge was 14.5 days (range, 6 to 20; mean, 13.68). The median time interval between onset of symptom to discharge was 19 days (range, 7 to 25; mean, 18.14) and the median time interval between onset of symptom to nucleic acid test turn positive after discharge (the last test was positive) was 26 days (range, 14 to 37; mean, 26.05). The median time interval between the discharge to nucleic acid test turn positive (the last test was positive) was 7.5 days (range, 1 to 14; mean, 7.91) and the median time interval between the diagnosis to nucleic acid test turn positive (the last test was positive) was 21 days (range, 13 to 29; mean, 21.61).
