Pneumonia Due to Human Coronavirus OC43 in an Immunocompetent Adult Detected by Multiplex Polymerase Chain Reaction

Figures

• 

  Figure 1.. Chest CT (a) shows pan-lobular GGO in the bilateral lower lobes on the day of admission. GGO in the bilateral lower lobes had disappeared on chest CT (b) on day 14 after leaving the hospital.

  Figure 2.. Real-time reverse transcription polymerase chain reaction for four HCoVs (HCoV-229E, HCoV-HKU1, HCoV-NL63, and HCoV-OC43). The blue line shows the findings for the present specimen. The red line indicates a positive control, and the green line indicates a negative control. HCoV-OC43 was detected in the nasopharyngeal swab of the patient.
