Hepatitis B can be transmitted sexually, but not only through sexual transmission, but also through mother-to-child and blood transmission. 1. Mother-to-child transmission: If the mother is a hepatitis B patient, the hepatitis B virus can be transmitted vertically to the newborn through intrauterine infection or during labor and delivery. 2. Blood Transmission: Hepatitis B infection can occur when an individual receives a blood transfusion with blood or blood products infected with the Hepatitis B virus. 3. Sexual transmission: Healthy individuals who have unprotected sex with a person who has hepatitis B are at risk of contracting the virus. Ordinary people can take blood test for hepatitis B surface antibody to see if they have protective antibody, and those who are negative for hepatitis B surface antibody can get hepatitis B vaccination in time. For those who have abnormal hepatitis B, they should go to the hospital in time and follow the doctor’s instructions for medication.
