What is the prevalence of hepatitis B (HBV) in newborns?
A chronic infection develops in the vast majority of newborn infants infected with the hepatitis B virus, compared with fewer than 10% of infected adults. The reason is probably related to the immaturity of the newborn immune response to infection, resulting in failure to completely eradicate the virus from hepatocytes.
What causes HBV infection in newborns?
Neonatal Hepatitis B Virus (HBV) Infection. Of the recognized forms of primary viral hepatitis, only hepatitis B virus (HBV) is a cause of neonatal hepatitis. Neonatal infection with other viruses (eg, cytomegalovirus, herpes simplex virus) may cause liver inflammation along with other manifestations.

Etiology. The risk of transmission is 70 to 90% from women seropositive for hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg—see Overview of Acute Viral Hepatitis : Serology) at the time of delivery. Women without the e antigen or with anti-HBe transmit the infection only 5 to 20% of the time.
