HCV Infection Challenges
Increasing reported incidence of acute and chronic HCV infection among persons aged 20-39 years over the past decade affects the number of pregnant women with HCV infection and infants who are exposed to HCV at birth.1 CDC’s recommendations to screen pregnant women for HCV infection during each pregnancy may aid practitioners in identifying HCV-infected mothers, which can lead to treatment for the mother during the postpartum period, and identify infants who should receive testing at a pediatric visit. The risk of an HCV-infected mother transmitting infection to their infant is approximately 6% per pregnancy, but the risk is higher if the mother has a high viral load or is coinfected with HIV.2 There are currently no treatments approved for use in pregnancy to prevent transmission of HCV infection to infants.
CDC recommends screening pregnant women during each pregnancy, and testing infants born to mothers with HCV infection. Follow-up of this group to determine if the infant has hepatitis C can be challenging. Testing infants consists of HCV RNA testing at or after age 2 months or anti-HCV testing at or after age 18 months.3,4
No recommended curative treatments are FDA approved for pregnant women or young children (aged <3 years), but curative treatment is approved for older children (aged ≥3 years) and women who are not pregnant (which can be given before or after pregnancy).
More studies are needed on the safety and efficacy of curative HCV treatments for pregnant women and young children.
