Patient's question:
There is a colleague who used to have hepatitis B surface antigen positive (), and now it seems to have improved. However, due to work reasons, I often have to have dinner with him. We usually use public chopsticks, but not always 100% of the time. I don’t have antibodies. How high is the risk of infection for me? I am currently getting vaccinated, but it is said that not everyone can be vaccinated. If there are children here, what should be noted? Thank you.Doctor's answer:
The hepatitis B virus is present in body fluids such as blood, semen, menstrual fluid, vaginal secretions, saliva, milk, tears, urine, and sweat of hepatitis B patients. The acute phase of acute hepatitis B and the acute recurrence phase of chronic hepatitis B are the most infectious. Patients with non-yellow jaundice hepatitis are 5 to 10 times more common than those with yellow jaundice hepatitis. Due to the lack of jaundice, the onset is less easily detected, making its infectivity more dangerous. Additionally, about 10% to 20% of the Chinese population are chronic HBsAg carriers; particularly those who show "big three positive" in hepatitis B serological indicators are a significant source of infection.
