Hepatitis B Is a Global Problem
Hepatitis B virus (HBV) is a highly contagious viral infection that can cause liver damage. The virus is easily spread via hep B–positive blood, semen or other body fluid. Pregnant women who have hepatitis B can also transmit the virus to their babies, usually during birth. People who have not been infected with HBV can be vaccinated against the virus to prevent infection.
Approximately 240 million people in the world are chronically infected with hepatitis B.
