The findings of CO-RADS score for grading of CT chest [12].

CO-RADS score	CT finding
CO-RADS 1	CT is normal or there are findings indicating a noninfectious disease
CO-RADS 2	The level of suspicion of COVID-19 infection is low, and CT findings are consistent with other infections
CO-RADS 3	The presence of COVID-19 infection is unknown or inconclusive, and CT abnormalities suggest infection, but it is unclear whether COVID-19 is involved or not
CO-RADS 4	The level of suspicion is high, and most CT findings, such as unilateral ground-glass, confluent, or multifocal consolidations without a typical site or any other characteristic findings, are suspicious but not typical
CO-RADS 5	The level of suspicion is high with typical CT findings
CO-RADS 6	RT-PCR positive for SARS-CoV-2
