Epidemiological characteristics of COVID-19 patients in convalescence period 2020-06-03 .txt text/plain 3783 179 54 The discharged patients must meet the following criteria: (1) the body temperature returns to normal for more than 3 days; (2) respiratory symptoms improve significantly; (3) pulmonary imaging shows that the acute exudative lesions were significantly absorbed and improved; (4) the SARS-CoV-2 ribonucleic acid (RNA) detection results of two consecutive respiratory specimens are negative (sampling interval should be at least 24 h). We recorded the clinical manifestations, RNA detection results of oropharyngeal swab specimens, SARS-CoV-2 IgM−IgG antibodies detection results (data were collected on the 28th day after discharge), chest computed tomography (CT) images and medication of these patients. A case report of four mild-to-moderate COVID-19 patients (all were medical staff) showed that all convalescent patients without clinical symptoms presented RP findings of RNA detection in throat swab specimens at 5−13 days after discharge [14] . Another study found that among 62 COVID-19 convalescent medical staff, two patients without clinical symptoms showed RP findings of RNA detection in throat swab specimens at 5−6 days after discharge [15] . ./cache/cord-330954-ft14aa2n.txt ./txt/cord-330954-ft14aa2n.txt
