Methods
We performed a retrospective review of the medical records of patients
with COVID-19 who were admitted to Shenzhen Third People’s Hospital
during January and February 2020, after that the disease had spread to
many cities in China, resulting in an inability to determine whether
patients got virus infection in Wuhan or other places. In this study we
defined the patients who had a history of traveling in Wuhan as WH
patients, and those who did not have this history as NWH patients. We
analyzed these two groups of patients for clinical characteristics,
including cardio-pulmonary function, hepatic function, hemogram,
immunologic parameters, viral load and duration, and severity of
illness. This study was approved by the Ethics Committee of Shenzhen
Third People’s Hospital.
SPSS 18.0 and GraphPad Prism 7 were used to analyze the data, andP <0.05 was considered to be statistically significant.
Continuous variables were expressed as the median and interquartile
range and categorical variables were expressed as numbers and
percentages. Unpaired t tests were used to compare continuous variables
and the chi-square or Fisher’s exact test was utilized to compare the
proportions of the categorical variables.
