In just 2 months, the virus has spread from Wuhan to the rest of China and another 33 countries. A novel coronavirus (severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2) was suspected to be the cause, with Phinolophus bat as the alleged origin ( 2). Since December 2019, a number of cases of “unknown viral pneumonia” related to a local seafood wholesale market were reported in Wuhan City, Hubei Province, China ( 1). Twenty-four of 57 patients (42%) showed improvement on follow-up chest CT scans before the RT-PCR results turned negative. Of the 1014 patients, 60% (34 of 57) to 93% (14 of 15) had initial positive CT scans consistent with COVID-19 before (or parallel to) the initial positive RT-PCR results. At analysis of serial RT-PCR assays and CT scans, the mean interval between the initial negative to positive RT-PCR results was 5.1 days ± 1.5 the mean interval between initial positive to subsequent negative RT-PCR results was 6.9 days ± 2.3. Of those 308 patients, 48% (103 of 308) were considered as highly likely cases and 33% (103 of 308) as probable cases. In the 413 patients with negative RT-PCR results, 308 of 413 (75%) had positive chest CT findings. The sensitivity of chest CT in suggesting COVID-19 was 97% (95% confidence interval: 95%, 98% 580 of 601 patients) based on positive RT-PCR results. Of the 1014 patients, 601 of 1014 (59%) had positive RT-PCR results and 888 of 1014 (88%) had positive chest CT scans.
