Chronic hepatitis C virus (HCV) infection represents a crucial health problem in children that greatly influence their quality of life. Many efforts have been directed toward the investment of effective drugs with high safety profiles and with oral administration for better compliance. The development of a new direct-acting antiviral (DAA) made it possible to achieve these goals.
