Is Cirrhosis Contagious?

Cirrhosis itself is not contagious. It is a chronic, progressive, and diffuse liver disease that represents the end stage of various underlying liver conditions. Over time, these conditions cause widespread liver cell damage, leading to excessive growth of fibrous tissue, the formation of regenerative nodules and pseudo-lobules, and ultimately, disruption of the liver's normal structure and blood supply.

Because cirrhosis is the final stage of long-term liver damage, it does not spread from person to person. However, some of the causes of cirrhosis can be infectious. For example, chronic viral hepatitis—such as hepatitis B or C—can lead to cirrhosis if left untreated over many years.

While cirrhosis itself cannot be passed on, hepatitis B and C are contagious viral infections. These viruses can be transmitted through contact with infected blood or other bodily fluids, potentially leading to new cases of hepatitis in others. In turn, those infections could progress to cirrhosis in the future.

In summary, cirrhosis is not a communicable disease, but it's important to be aware that certain underlying causes, like hepatitis B and C, can indeed be transmitted. Proper prevention and early treatment of viral hepatitis are key to reducing the risk of developing cirrhosis later on.
