Hepatitis B is a worldwide disease, placing a significant burden on

healthcare systems. The majority of people carrying hepatitis B virus

in Vietnam are transmitted from mother to child. Whether the delivery

method of HBV-infected women affects the transmission of the virus

to the baby is a very important issue. Because it will help obstetricians

choose the appropriate method to end pregnancy to minimize the risk

of adverse effects for mother and child. With the goal of

understanding the impact of HBV DNA load on the method of

delivery and the risk of transmitting the virus to the baby of HBVinfected

pregnant women, we conducted research on 80 research

subjects. Using the cross-sectional descriptive method, we have

obtained the following results: HBV DNA load is not related to the

method of delivery (cesarean section or vaginal birth); HBV DNA

load of maternal blood is closely related to HBsAg (+) status in

umbilical cord blood.
