Hepatitis B
Book AppointmentHepatitis B is a viral infection of the liver caused by the hepatitis B virus (HBV). The liver plays an important role in filtering the blood, processing nutrients, and fighting infections. When infected, the liver becomes inflamed and may not function properly.
The hepatitis B virus (HBV) spreads through contact with infected blood or certain body fluids (like saliva, semen, and vaginal fluid). It can also be passed from an infected mother to her baby during childbirth.
Hepatitis B can be:
Acute (short-term): Most people recover within a few months.
Chronic (long-term): In some people, the virus remains in the body and can lead to serious liver disease, including cirrhosis (scarring of the liver), liver failure, or liver cancer.
