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.
