Hepatitis C is a virus that can harm the liver. It is usually spread through blood-to-blood contact, such as from an infected mother to her baby during birth or from sharing needles. While hepatitis C may not cause symptoms in children, regular checkups are important to monitor liver health. There is no way for a mother to prevent passing hepatitis C to her baby. The virus can remain in the body for life, though medications exist as a cure once one is an adult.
