Perinatal Hepatitis B Statistics
Perinatal transmission from an infected mother to her infant at birth is one of the most serious and effective modes of transmitting hepatitis B virus (HBV). The risk of infection to the infant may be as high as 70-90%. Up to 90% of perinatally infected babies who are not treated with vaccine will develop a chronic hepatitis B infection. An estimated 15-25% of these infants will ultimately die of liver failure secondary to chronic hepatitis, liver cirrhosis, or primary liver cancer. Treatment initiated within 12 hours after birth is up to 90% effective at preventing this serious infection.
The Minnesota Department of Health (MDH) tracks infants born to hepatitis B positive mothers. Over a 10-year period, there has been a steady increase of the number of infants born to hepatitis B positive mothers. Of these infants over 90% have received vaccine at birth. Continued success depends upon maintaining high immunization rates.
