[Viral hepatitis and pregnancy].

VIRAL HEPATITIS AND PREGNANCY. The event of pregnancy, the risks of obstetrical complications and vertical transmission will vary according to the type of viral hepatitis. Hepatitis A is transmitted via feacal-oral transmisson, is generally mild, but may increase the risk of obstetric complications. Hepatitis B, the most common, can be transmitted from mother to child, particularly during delivery. Its management includes prenatal screening and antiviral treatment to prevent vertical transmission. Hepatitis C is mainly blood-borne. Hepatitis D superinfects those with HBV, with limited treatment options during pregnancy. Hepatitis E, common in low-income countries, is severe particularly in the third trimester, and may lead to fulminant hepatitis. Mother-to-child transmission is rare for all these viruses, and breastfeeding is generally permitted.
