A total of 166 patients were enrolled in this study. Excluding 2 cases younger than 18 years old, 28 cases with normal CT presentations, 2 cases with underlying lung disease, 2 cases with onset to consultation over 14 days, and 2 cases could not perform chest CT because of pregnancy, finally 130 cases were included in the statistical analysis with 54 cases positive and 76 cases negative (see Figure 1 ). As shown in Table 1 , the mean age of positive group patients was 45.1 ± 13.4 years, while age ranged from 19 to 77 with 28 males (51.9%). The average time from symptoms onset to the first visit was 4 days. For the negative group patients, the average age was 41.8 ± 13.6 years, while age ranged from 19 to 81 with 49 males (64.5%). The average time from the onset of symptoms to the first visit was 3 days. It was found that proportion of Wuhan residence history and clustering incidence between two groups were statistically significant (P<0.05), while the remaining variables were not significant.
