Neonatal hepatitis b virus (hbv) infection


  • Neonatal hepatitis B virus infection is usually acquired during delivery. It is usually asymptomatic but can cause chronic subclinical disease in later childhood or adulthood. Symptomatic infection causes jaundice, lethargy, failure to thrive, abdominal distention, and clay-colored stools. Diagnosis is by serology. Rarely, severe illness may cause acute liver failure requiring liver transplantation. Less severe illness is treated supportively. Active and passive immunization help prevent vertical transmission.
    (See also Overview of Acute Viral Hepatitis in adults and Overview of Neonatal Infections.)
    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.
