Vertical transmission of hepatitis B means transmission

  • A.from mother to infant around the time of birth
  • B.between adults through sexual contact
  • C.through contaminated food and water
  • D.by an insect vector from person to person

Answer: A

Correct answer: from mother to infant around the time of birth

Vertical transmission occurs chiefly at delivery, through contact with maternal blood and secretions, rather than across the placenta. That timing is what makes intervention possible: vaccine and immune globulin given to the infant within hours of birth prevent most infections.
