Staying Hep B Free: Prevention, Vaccination, & More

What is Hepatitis B?

Hepatitis B is an infection of the liver caused by the hepatitis B virus (HBV). Infection with HBV can be both acute (short-term) and chronic (lasting), and may result in severe liver damage and inflammation. The HBV virus is 50-100 times more contagious than HIV. An estimated 240 million people are chronically infected with hepatitis B, and nearly 20,000 new cases are diagnosed each year.
