Girlfriends with hepatitis B can usually kiss (neither party has symptoms such as mouth ulcers, bleeding gums, etc.), and the hepatitis B virus is not usually transmitted through kissing.
Hepatitis B is usually transmitted through three ways, namely, mother-to-child transmission, blood and body fluids transmission, and sexual transmission:
1. Mother-to-child transmission: including intrauterine infection, i.e., acquired through the placenta; perinatal transmission or transmission during labor and delivery, due to contact of broken skin or mucous membranes with mother’s blood, amniotic fluid, vaginal secretions, etc.; post-delivery transmission, mainly due to close contact between mother and baby.
2. Blood and body fluid transmission: such as blood transfusion, blood products, sharing syringes and razors.
3. Sexual transmission: unprotected sex with hepatitis B patients, especially multiple sexual partners, the risk of hepatitis B infection increases.
Kissing does not usually belong to any of the above three ways, so kissing usually does not transmit hepatitis B.
