Demographics and baseline characteristics of WH patients and NWH
patients
Fifty-nine patients who had a history of traveling in Wuhan and 53
patients who did not travel during January and February in 2020 were
enrolled. As shown in Supplemental Table 1, female patients seemed to be
more predominant in NWH patients (30/53, 56.6%) than in WH patients
(22/59, 37.3%). The mean and median
age of WH patients were 42.69 and 42, respectively, which were higher
than that of NWH patients, but there was no significant difference. WH
patients had a similar percentage of comorbidities with NWH patients.
The incubation period of SARS-Cov-2 was similar in these two groups
(9.44 d vs 9.08 d). WH patients seemed to have a higher percentage of
shivering, cough, nasal obstruction, and sore throat than NWH patients.
We also observed that the percentage of severe to critical cases in WH
patients was significantly higher than that in NWH patients
(P<0.05) (Figure 1A). In addition, two death cases occurred in
WH patients.
