Vertical and early childhood transmission are important because infection acquired early in life is more likely to become chronic. Pregnancy is a critical point for HBV prevention because mother-to-child transmission can occur, especially around delivery. Perinatal transmission is the main clinical and public health concern for HBV during pregnancy. Without preventive measures, newborn transmission risk is estimated at 70% to 90% when maternal viral load is high or the mother is HBeAg-positive.
