Sequential changes of SARS-CoV-2 PCR of oropharyngeal swab specimens in 12 patients with COVID-19. The alphabetic is the case No. and numerical values are the illness days of oropharyngeal swab sampling after the day of confirmed diagnosis of COVID-19 (D0). Black boxes indicate positive PCR results, and the boxes with dots negative results. The dotted circles show the gap intervals between two de-isolation criterion of two and three consecutive negative real-time polymerase–chain reaction results of oropharyngeal swabs.
