Hepatitis BHepatitis B is one type of hepatitis, a liver disease caused by the hepatitisB virus (HBV). Hepatitis B spreads by contact with an infected person'sblood, semen or other body fluid. An infected woman can give hepatitis B toher baby at birth. If you get HBV, you may feel as if you have the flu, or youmay have no symptoms at all. A blood test can tell if you have it.
