Patient's question:
Someone in my family has hepatitis B, and I recently got a mouth ulcer. Will I get infected if we eat dinner together?Doctor's answer:
If the other person has oral ulcers, it is possible to be infected. Hepatitis B is mainly transmitted through blood, semen, and vaginal secretions when the skin or mucosa of an infected person has a wound. Of course, sexual activity can lead to infection. Additionally, transmission can occur from mother to child or father to child. The best way to prevent it is to get vaccinated against hepatitis B. Before antibodies develop, it's best to wear condoms. Generally, sexual activity is not likely to result in infection. However, if both parties have oral ulcers, cracked lips, broken skin, or wounds, and engage in sexual activity or share eating utensils, the risk of infection increases.
