Dr. Shen Yonghua
Hepatitis B is an infectious disease caused by the hepatitis B virus. Its transmission routes mainly include the following:
1. **Bloodborne transmission**: The hepatitis B virus spreads through direct contact with the blood of an infected individual. This includes the use of unsterilized needles, blood transfusions, or blood products.
2. **Sexual transmission**: The hepatitis B virus can be transmitted through unprotected sexual contact. Infected individuals' body fluids, such as semen and vaginal secretions, may contain the virus.
3. **Mother-to-child transmission**: An infected mother may transmit the virus to her newborn during childbirth. This transmission route is called vertical transmission and usually occurs during labor or through breastfeeding.
Important measures for preventing hepatitis B include vaccination against hepatitis B, avoiding the use of unsterilized needles, practicing safe sex, and implementing preventive measures for mother-to-child transmission. If symptoms of hepatitis B appear or there is a risk of infection, prompt medical attention is recommended.
