Do hepatitis B virus carriers pose a risk of transmission in daily life?

Generally speaking, the term "hepatitis B virus" refers to the hepatitis B virus (HBV). HBV carriers may transmit the virus to others in daily life. The specific analysis is as follows:

HBV carriers refer to individuals who have been infected with HBV but have normal liver function and no significant liver damage. As they carry the hepatitis B virus in their bodies, they are infectious to a certain extent. The main transmission routes of HBV include blood transmission, mother-to-child transmission, sexual transmission, and iatrogenic transmission. Therefore, routine social contacts in daily life, such as handshaking, hugging, sharing office supplies, studying in the same classroom, or dining in the same restaurant, generally do not lead to HBV transmission.

However, if the blood of an HBV carrier comes into contact with another person's broken skin or mucous membranes—for example, through sharing personal items such as razors or toothbrushes—it may lead to viral transmission. Additionally, during medical procedures such as blood transfusion or organ transplantation, if medical instruments or blood products that have not been strictly sterilized are used, HBV transmission may also occur. If HBV carriers engage in unprotected sexual activity with uninfected individuals, the virus may be transmitted through bodily fluids such as semen or vaginal secretions.

In daily life, it is important to maintain good personal hygiene habits, such as washing hands frequently and avoiding touching the eyes, nose, and mouth with unwashed hands.
