Hepatitis C virus (HCV) can transmit vertically from mothers to neonates, with higher risks in HIV-positive mothers or those with high viral loads. Breastfeeding does not appear to increase HCV transmission risk to infants.

Area of Science:

  • Hepatology and Virology
  • Infectious Diseases Epidemiology
  • Maternal-Fetal Medicine

Background:

  • Hepatitis C virus (HCV) infection poses risks for vertical transmission to neonates.
  • Understanding transmission dynamics is crucial for clinical management and infant outcomes.

Purpose of the Study:

  • To review the epidemiology and clinical course of HCV infection.
  • To examine data on vertical transmission of HCV to neonates.
  • To develop recommendations for neonate follow-up.

Main Methods:

  • Literature review of English-language studies from 1988-1996 via MEDLINE.
  • Analysis of case series on vertical HCV transmission in neonates using HCV RNA testing.
  • Summarization of data regarding maternal HIV status and HCV chronicity.

Main Results:

  • Vertical transmission rates ranged from 0-18% in HIV-negative mothers and 6-36% in HIV-positive mothers.
  • Transmission risk correlated with maternal HCV RNA levels, increasing with higher viral loads.
  • No documented cases of HCV transmission via breastfeeding were found.

Conclusions:

  • Vertical transmission of HCV affects up to 18% of pregnancies in HCV-positive, HIV-negative women and 6-36% in HCV-positive, HIV-positive women.
  • High maternal HCV RNA levels and concurrent HIV infection significantly increase transmission risk.
  • Breastfeeding is not associated with vertical HCV transmission.
