Blood borne viruses

Blood borne viruses (BBVs) are viruses found in the blood of infected individuals. Some BBVs are also present in other bodily fluids such as semen, vaginal fluid and breast milk. The main BBVs are human immunodeficiency (HIV), hepatitis B and hepatitis C.

BBVs can be passed from person to person, through unprotected sex or by sharing needles and other paraphernalia to inject drugs. Infected mothers can also transmit some BBVs to their baby during childbirth. Transmission via blood transfusion or from products made with infected blood can also occur. The screening of all donated blood in the UK virtually eliminates the risk of transmission via this route although BBVs may still be acquired through these procedures in countries where the blood supply is not screened.

Some occupations (i.e. some healthcare workers, prison officers etc) may have an increased risk of exposure to BBVs in the course of their duties.

Blood borne viral hepatitis action plan for Wales

Public Health Wales with the support of the Welsh Government has developed a 'Blood borne viral hepatitis action plan for Wales'. The key aims of the action plan include:

• reducing the transmission of hepatitis infection in Wales
• increasing the diagnosis of current infection
• improving the provision of treatment and support to infected individuals.
