Hepatitis B is a major cause of chronic liver disease and can cause cirrhosis, liver failure

and hepatocellular carcinoma. As many as 240 million of them have chronic hepatitis B and

780,000 people have died due to acute and chronic complications of hepatitis B.

Transmission of hepatitis B can occur in the fetus it contains. The efforts to prevent vertical

transmission can be done in the form of screening in pregnant women in the first trimester

of pregnancy as well as giving immunoglobulins to infants after 12 hours of birth. The form

of nursing care given to individuals for the prevention of infectious diseases must be

provided comprehensively with the aim of the client being able to adapt to his illness and

have good behavior. The management of pregnant women with hepatitis B using Roy's

Adaptation Theory and the Health Belief Model (HBM) aims to provide knowledge and

improve client behavior regarding the prevention of disease transmission to infants and

other families.
