Hepatitis B can be contracted through sexual contact. Hepatitis B has multiple modes of transmission and requires active prevention and treatment. Saliva, semen, sweat, vaginal secretions, breast milk and other body fluids contain the hepatitis B virus. If one partner has broken genitals and carries a high number of hepatitis B viruses, and the other partner has broken skin and mucous membranes in the mouth, there is a risk of hepatitis B infection when both partners engage in oral sex. Healthy people are advised to take precautions when having sexual contact with a person with hepatitis B to prevent infection. Hepatitis B virus can also be transmitted through blood and vertically from mother to child. If hepatitis B patients need to conceive, they also need to consider the possibility of hepatitis B transmission to their offspring and consult their doctors in advance. It is recommended that the discovery of hepatitis B should go to a regular hospital in a timely manner, timely and standardized treatment, which is beneficial to themselves and others.
