How do people get infected ?

Hepatitis B virus is transmitted by contact with blood or body fluids of an infected person in the same way as human immunodeficiency virus (HIV), the virus that causes AIDS. However, HBV is 50 to 100 times more infectious than HIV.

The main ways of getting infected with HBV are:

Perinatal (from mother to baby at the birth)
Child-to-child transmission
Unsafe injections and transfusions
Sexual contact
Worldwide, most infections occur from infected mother to child, from child to child contact in household settings, and from reuse of unsterilized needles and syringes. In many developing countries, almost all children become infected with the virus.read more
