Hepatitis B is an infectious illness of the liver caused by a virus.
Some people have the hepatitis B virus in their body but cannot
get rid of it. They can still infect other people and are known
as carriers. The disease is spread by the virus entering the body
following contact with body fluids, most often blood, from an
infected person.
If the mother is a carrier of the virus she can pass the virus to her
baby at birth. It is also possible to catch the virus from a carrier
through, for example, unprotected sex, shared injection needles or
treatment with medical equipment which has not been properly
