Introduction
The outbreak of COVID-19, caused by SARS-CoV-2, in Wuhan city in China since December of 2019 has led to more than 80,000 infection cases and 4600 death cases in China and 4 million infection cases and 280,000 death cases worldwide1,2. Several papers have retrospectively analyzed the clinical characteristics of patients including children, the deceased, those who have recovered, and individuals with hypertension3-7. However, there are not yet reports on the comparison in clinical characteristics between patients with a travel history in Wuhan and patients without such experience in the early stage of pandemic.
In this study, we analyzed patients who had a history of traveling in Wuhan and patients who did not travel during January and February 2020 in Shenzhen Third People’s Hospital. According to their clinical characteristics and laboratory parameters, we observed that patients with travel history in Wuhan had some differences in viral duration and T cell level when comparing with their counterparts.
