Fig. 2. Trends of Ct values of 31 patients with follow-up SARS-CoV2-PCR tests (A) and comparison of the severity of COVID-19 between patients in convalescent period and patients in early infection period (B). The trend lines of the recovery period were indicated by solid lines, and the trend lines of the early infection period were indicated by dotted lines. Ct, cycle of threshold; PCR, polymerase chain reaction.

Fig. 2. Gram-stained microscopy of smear and subculture plates of positive blood culture vials. (A) Slender gram-negative bacilli with a clump of those (Gram stain, 1,000×). Rough (B) and smooth (C) colonies on blood agar plate and colorless colonies of MacConkey agar plate after 2 days of incubation.

Fig. 1. Clinical and laboratory course of this case during hospitalization. The patient developed high fever at the second day of hospitalization (A). Chest computed tomography showed a 2.8 cm low attenuating mass (indicated with arrowheads) with internal punctate calcification in the left lower lobe at that day (B, middle) and 64 days prior to hospitalization (B, upper). The lung mass was not significantly changed at 106 days after discharge (B, lower)
