Patient's question:
From primary school to the first year of high school, I kept getting the hepatitis B vaccine. After that, I didn't get any more shots. During my three years of high school, my roommate had hepatitis B, and I once used his towel and toothpaste. What is the probability that I got infected?Doctor's answer:
According to your description, the main routes of hepatitis B transmission are bloodborne mother-to-child transmission. If mouth ulcers come into contact with the saliva of a hepatitis B patient, it can also lead to infection. It is recommended that you get tested for the five hepatitis B markers at the hospital. If you have antibodies, you will not be infected with the hepatitis B virus. Using a hepatitis B patient's towel and toothpaste carries a certain level of infectivity. However, considering that you have previously received the hepatitis B vaccine, it is possible that you have antibodies. It is recommended that you check the titer of your antibodies. If you have not been infected with the hepatitis B virus and your hepatitis B antibody titer is low, it is advisable to receive a booster dose of the hepatitis B vaccine.
