The rate of mother-to-infant transmission for hepatitis C virus is estimated to be around 5% of viraemic mothers and represents an important route of HCV infection among children. Transmission is possible in utero but the highest risk of infection is at or near the time of delivery because of an important blood transmission of hepatitis C virus. Mothers with high levels of HCV-RNA and co-infected for human immunodeficiency virus are documented to have risk factors for vertical transmission of HCV. Thus, for these, the mode of delivery must be discussed even if there are no precise recommendations. Among obstetrical risk factors, the results of literature fail to prove a benefit of elective caesarean delivery in the aim to reduce the vertical transmission of HCV. However, obstetrical situations with a high risk of blood contact between mother and foetus must be considered and if possible evicted.
