Patient's question:
A few weeks ago, one of my classmates had a thorough examination and was found to have chronic hepatitis B (HBeAg positive). We live in the same dormitory, but she doesn't show any symptoms in her daily life. How can we prevent it?Doctor's answer:
The hepatitis B virus can never be contracted through normal living and daily interactions, including sharing meals. Hepatitis B is only transmitted through blood, mother-to-child transmission, and sexual contact. The best way to prevent hepatitis B infection currently is to get vaccinated, which generates protective antibodies. Hepatitis B virus carriers can be divided into two categories: those with normal liver function, who are healthy carriers and do not require treatment, as their risk of developing liver cancer or cirrhosis is no different from that of the general population; if liver function repeatedly becomes abnormal.
