What are the effects of untreated hepatitis B?

Untreated hepatitis B can lead to serious complications, including:

* Chronic hepatitis B: This is when the infection lasts for more than six months. It can cause liver damage, inflammation, and scarring (cirrhosis).

* Liver failure: This is when the liver stops working properly. It can be caused by acute hepatitis B, chronic hepatitis B, or cirrhosis.

* Liver cancer: This is the most serious complication of hepatitis B. It is the leading cause of liver cancer worldwide.

* Other complications: These can include kidney disease, pancreatitis, and vasculitis.

Hepatitis B can be prevented with a vaccine. The vaccine is safe and effective and is recommended for all infants, children, and adults who are at risk of infection.
