Question
If a mother is positive for Hepatitis B during pregnancy, what precautions should be taken to prevent transmitting the virus to the fetus?
Answer
During pregnancy, mothers who test positive for Hepatitis B should undergo regular checks and receive high-titer Hepatitis B immune globulin injections in the 7th, 8th, and 9th months of pregnancy to reduce the risk of virus transmission to the fetus. After birth, newborns should be administered high-titer Hepatitis B immune globulin immediately and then vaccinated according to the 0, 1, and 6-month immunization schedule one week later, which can effectively prevent vertical transmission of the Hepatitis B virus. Additionally, mothers who are positive for Hepatitis B should not breastfeed their newborns.
