Epidemiological Study and Clinical Characterization of COVID-19 Cases in Xuzhou, China

ABSTRACT

In this paper, an epidemiological study was performed by focusing on all confirmed patients with COVID-19 in Xuzhou, a prefecture-level city, and a transportation hub with 10.44 million population in the east region of China. The median age of the patients is 42-year-old and 45.57% are male;25 cases (31.65%) are imported. 23 cases (29.11%) were confirmed between January 26 to 31, 2020 while 56 cases (70.89%) were from February 1 to 16, 2020. Among the ten administrative divisions of Xuzhou city, Suining county (n=31) and Pizhou City (n=15) have the most cases while Tongshan district has none. A representative familial cluster with 6 cases was analyzed in detail in order to get a better understanding of the transmission routes of the virus. Furthermore, we performed a retrospective, single-centre study of 41 COVID-19 patients at Xuzhou Infectious Diseases Hospital in terms of clinical findings, which provided an insightful understanding of the disease.
