Patient's question:
I just found out; the doctor said my friend has chronic hepatitis B.Doctor's answer:
The main routes of hepatitis B transmission are as follows:1. Bloodborne transmission: This primarily includes surgical procedures, blood products, needle sticks, acupuncture, dental and surgical instruments, and other medical practices, as well as high-risk cosmetic procedures.
2. Mother-to-child transmission: This refers to the transmission of the hepatitis B virus from a mother carrying the virus during pregnancy, childbirth, or breastfeeding to her infant. Surface antigen-positive mothers have a 40%-50% chance of transmitting the virus to their infants, while mothers who are positive for both surface antigen and e antigen have a 90%-100% chance.
3. Sexual transmission: Sexual activity between men and women can spread the hepatitis B virus through semen and vaginal secretions.
4. Close contact transmission
