Positive reverse transcription-polymerase chain reaction assay results in patients recovered from COVID-19: Report of two cases

Figure 1 Date of clinical symptoms and hospitalization. RT-PCR: Reverse transcription-polymerase chain reaction.

Figure 2 Computed tomography images of the 58-year-old woman during her first hospitalization and during rehospitalization. A and B: Ten days after symptom onset, computed tomography (CT) showed patchy bilateral subpleural ground-glass opacities (GGO); C and D: Twelve days after symptom onset, the subpleural GGO decreased and evolved into linear opacities; E and F: Seventeen days after symptom onset, there was a further reduction of GGO and predominance of linear opacities; G and H: CT performed 38 d after symptom onset showed near complete resolution of pulmonary opacities (orange arrow, G).

Figure 3 Computed tomography images of the 16-year-old man with coronavirus disease 2019 obtained during rehospitalization. Thirty-one days after symptom onset, computed tomography showed minimal ground-glass opacity and linear opacities (orange arrow).
