Hepatitis C

Hepatitis C infection is caused by a virus that attacks the liver. It is transmitted primarily through blood-to-blood contact with an infected person, including through sharing needles or other drug-related equipment and from mother to baby at birth. Hepatitis C can cause both acute and chronic infection, often without symptoms. Chronic infection can lead to serious liver disease or cancer. There is currently no vaccine to prevent hepatitis C, although effective therapy is now available.
