There are multiple definitions:
mother-to-child transmission [of HBV](English)
- transmission of hepatitis B virus (HBV) remains the major risk factor for chronic HBV infection worldwide. Antiviral therapy improves HBV suppression and reduces MTCT in women with chronic HBV infection with high viral load compared to the use of hepatitis B immunoglobulin and vaccination alone; the use of telbivudine, lamivudine, and tenofovir appears to be safe in pregnancy with no increased adverse maternal or fetal outcome
