Risk factors and Complications of Hepatitis C

Risk factors

Your risk of hepatitis C infection is increased if you:

Are a health care worker who has been exposed to infected blood, which may happen if an infected needle pierces your skin
Have ever injected or inhaled illicit drugs
Have HIV
Received a piercing or tattoo in an unclean environment using unsterile equipment
Received a blood transfusion or organ transplant before 1992
Received clotting factor concentrates before 1987
Received hemodialysis treatments for a long period of time
Were born to a woman with a hepatitis C infection
Were ever in prison
Were born between 1945 and 1965, the age group with the highest incidence of hepatitis C infection

Hepatitis C infection that continues over many years can cause significant complications, such as:

Scarring of the liver (cirrhosis). After 20 to 30 years of hepatitis C infection, cirrhosis may occur. Scarring in your liver makes it difficult for your liver to function.
Liver cancer. A small number of people with hepatitis C infection may develop liver cancer.
Liver failure. Advanced cirrhosis may cause your liver to stop functioning.
