Opportunities for Enhanced Prevention and Control of Hepatitis C Through Improved Screening and Testing Efforts

An estimated 2.4 million people in the United States are living with hepatitis C virus (HCV) infection. In 2020, the Centers for Disease Control and Prevention updated hepatitis C screening recommendations to test adults aged ≥18 years at least once in a lifetime and pregnant persons during each pregnancy. For those with ongoing exposure to HCV, periodic testing is recommended. The recommended testing sequence is to obtain an HCV antibody test and, when positive, perform an HCV RNA test. Examination of HCV care cascades has found that incomplete HCV testing occurs when a separate visit is required to obtain the HCV RNA test. Hepatitis C core antigen testing has been shown to be a useful tool for diagnosing current HCV infection in some settings. Hepatitis C testing that is completed, accurate, and efficient is necessary to achieve hepatitis C elimination goals.
