Hepatitis B virus survives in the cells of the human body, and it will be inactivated after leaving the human body for two or three hours, and it cannot survive in clothing. Hepatitis B virus can survive in human body fluids such as blood, saliva, semen, vaginal secretions, etc. In addition to liver cells, hepatitis B virus can survive in human body fluids such as blood, saliva, semen, vaginal secretions, etc. Therefore, contact with hepatitis B virus clothing will not transmit hepatitis B. Hepatitis B can be transmitted if a person does not have protective antibodies against hepatitis B, has a fresh wound, or has had unprotected sex with a hepatitis B patient, and comes into contact with the blood, semen, and vaginal secretions of a hepatitis B patient.
