Liver cirrhosis in the decompensated stage with ascites present is not inherently contagious. Whether the condition is infectious depends not on the severity of liver function, the degree of liver cirrhosis, or the gravity of ascites, but rather on the underlying cause of the liver cirrhosis. For example, liver cirrhosis caused by alcohol consumption is not contagious. However, if the liver cirrhosis is due to viral hepatitis, such as commonly seen with hepatitis B or C, the condition can be infectious. Therefore, the presence of ascites or liver cirrhosis itself is not an indicator of infectiousness; the crucial factor is whether there is an infectious virus present.
