Per CDC:
What is hepatitis B?
Hepatitis B is a serious liver infection caused by the hepatitis B virus. When babies become infected with hepatitis B, they have about a 90% chance of developing a lifelong, chronic infection. Left untreated, about 1 in 4 children who have chronic hepatitis B will eventually die of health problems related to their infection, such as liver damage, liver disease, or liver cancer.
Hepatitis B and Pregnancy
All pregnant women should get a blood test for hepatitis B as part of their prenatal care. Hepatitis B can be easily passed from a pregnant woman with hepatitis B to her baby at birth. This can happen during a vaginal delivery or a c-section. If you have hepatitis B, health care providers can give your baby a set of shots at birth to prevent your baby from getting infected.
