Hepatitis B
Hepatitis B is transmitted parenterally and sexually. Transmission most commonly occurs following sexual intercourse, as a result of blood to blood contact, including injury with contaminated sharp instruments or other equipment by intravenous drug misusers, or by perinatal transmission from mother to child.
Transfusion-associated infection is now rare and adequate treatment of blood products has eliminated these as sources of infection in the UK. A hepatitis B vaccine is available and routine immunisation of at-risk groups is recommended. These include certain groups of health care workers, babies born to hepatitis B positive mothers and injecting drug users.
Hepatitis B is a notifiable disease.

Hepatitis C
Infection with hepatitis C virus is associated with intravenous drug use or blood products. Sexual, vertical and occupational transmission do occur, but on a less frequent basis than HBV. Transfusion associated infection is now rare in the UK. A vaccine for hepatitis C is not available.
Hepatitis C became a notifiable disease in July 2021.
