| Additional Information | Hepatitis B is a serious viral infection that can lead to chronic liver disease and liver cancer (hepatoma). Individuals who are chronically infected are sometimes referred to as 'carriers'. They often have no, or minimal, symptoms associated with their infection. Cases are often linked to place of birth, or mother’s place of birth. The condition is very common in many parts of the world and vertical spread from mother to baby is often a major route of transmission. Hepatitis B may also be acquired by injecting drug use, sexual transmission and more rarely tattoos and piercings
