title: Infection of the fetus with hepatitis B e antigen via the placenta.
abstract: Evidence that hepatitis B e antigen (HBeAg) can pass through the human placenta has been questioned. We investigated 15 HBeAg-positive mothers who were hepatitis B carriers and their newborn babies, and found that HBeAg does indeed cross the human placenta.
