Patient 4 had a positive anal swab after discharge. This middle-aged male was admitted to the hospital because of fever (maximum body temperature 39.5 °C), cough, and dyspnea. His OBT was positive and he had positive throat swab samples for 12 days. The chest CT on admission (January 20, 2020) showed markedly reduced lung translucency, bilateral multiple GGO and consolidations and peripheral distribution (CT score = 13) (A-C). CT on discharge (February 10, 2020) showed lung transparency returned to normal and absorption of multiple GGO, but some irregular consolidations remained (CT score = 10) (D-E). CT after discharge (February 24, 2020) showed continuous absorption of multiple lesions, with only a small amount of GGO remaining (CT score = 7) (G-I)
