Whether cirrhosis is contagious or not is related to its etiology. Viral hepatitis causing cirrhosis is somewhat contagious, while alcoholic cirrhosis and simple fatty liver cirrhosis are usually not contagious. Cirrhosis is a relatively common clinical disease, mainly from long-term chronic hepatitis, such as hepatitis B, C virus infection, repeated liver inflammation damage gradually progressed to cirrhosis. Patients with cirrhosis of viral hepatitis are contagious, and the strength of the contagion is related to the strength of viral replication in the body. The higher the amount of virus, the more infectious it is. Cirrhosis can also come from long-term heavy alcohol consumption, autoimmune liver diseases such as autoimmune hepatitis, primary biliary cirrhosis, fatty liver, etc. Such cirrhosis is not contagious. So different causes of cirrhosis, contagious or not, are not exactly the same. Patients with cirrhosis must go to the hospital for treatment in time to keep the cirrhosis in a stable stage and avoid developing into a decompensated stage with symptoms such as ascites and portal hypertension.
