title: Prenatal transmission of hepatitis B virus to neonates born to serum hepatitis B virus DNA-positive mothers.
abstract: Hepatitis B virus (HBV) DNA was detected by in vitro enzymatic DNA amplification techniques in 66.7% (six of nine) of hepatitis B virus surface antigen (HBsAg)-positive and in 21.1% (7 of 33) of HBsAg-negative pregnant women. Five of the HBV DNA and HBsAg-positive women and one HBV DNA-positive but HBsAg-negative woman gave birth to infants positive for serum HBV DNA at time of birth. These results suggest that HBsAg-negative pregnant women are potentially capable of transmitting HBV DNA to their infants.
