Sharing meals with a patient with hepatitis B does not transmit hepatitis B because hepatitis B is mainly transmitted through the blood route. There is a risk of infection when sharing personal items such as toothbrushes, nail clippers, facial scrapers, razors, etc., which can be transmitted through broken skin, or syringes, which can be transmitted when sharing syringes with a patient with hepatitis B. There is also a risk of infection when sharing medical equipment that has not been strictly sterilized with a patient with hepatitis B for invasive testing and treatment. To be on the safe side, it is best to share meals with hepatitis B patients. In addition to the blood route of transmission of hepatitis B virus, vertical mother-to-child transmission and sexual intercourse are also risk factors for transmission of hepatitis B virus. Pregnant women with high viral load can transmit hepatitis B virus to their newborns without mother-to-child interruption.
