Clinical Characteristics of Hospitalized Patients with SARS-CoV-2 and Hepatitis B Virus Co-infection

In addition to the recent emerged SARS-CoV-2, hepatitis B virus (HBV) is one of the viruses which cause a global infection and threat public health. In worldwide, the prevalence of HBsAg is about 3.9% (Polaris Observatory 2018). According to a nationwide epidemiological survey of population whose ages range from 1 to 59 years in China, 2006, the prevalence of HBsAg was 7.2% (Liang et al. 2009). As SARS-CoV-2 and HBV both can cause liver damage (Fan et al. 2020), further understanding of the risk of SARS-CoV-2 on patients with HBV infection is urgently required in order to design an optimized treatment strategy. However, the impacts of SARS-CoV-2 infection on HBV patients are still not clear. For example, we do not yet know whether the SARS-CoV-2 infection is more severe in HBV patients and we also do not have much knowledge about the impact of SARS-CoV-2 on the course of HBV infection. In this retrospective study, we investigated the clinical characterizes of the patients coinfected with SARS-CoV-2 and HBV by analyzing the clinical records and laboratory tests of 123 COVID-19 patients admitted to Zhongnan Hospital of Wuhan University, Wuhan, China, from January 5 to February 20, 2020.
