A Clinical Cohort Study on the Pathogen Spectrum of Hepatic Virus-caused Cirrhosis Complicated With Infection

The goal of this observational study is to expound the population and characteristics of pathogenic microorganisms with co-infection, draw the pedigree of pathogenic microorganisms, and evaluate its influence on disease outcome in patients with hepatic virus-caused cirrhosis. The main questions it aims to answer are: * Describe the populations and characteristics of pathogenic microorganisms responsible for co-infections in patients with hepatic virus-caused cirrhosis. * Map the spectrum of pathogenic microorganisms, and evaluate their impact on disease regression.
