THE VIRUS. Hepatitis B is the worldâs most common liver infection. Hep B is a serious and potentially deadly liver infection. It is caused by becoming infected with the hep B virus (HBV). It can cause serious liver problems like inflammation, fibrosis, cirrhosis, and liver cancer. In the U.S., chronic (long-term) hep B affects many people.
The name of each type of viral hepatitis condition corresponds to the virus that causes it.
