Eating something that a person with hepatitis B has eaten is usually not contagious, but if both have broken mouths and bleeding, etc., the possibility of infection cannot be ruled out. Our country is a lot of people with hepatitis B. Hepatitis B is a disease caused by the infection of the body with the hepatitis B virus. Hepatitis B virus is contagious, hepatitis B virus transmission is mainly mother-to-child transmission, that is, vertical transmission, blood transmission, sexual transmission, transmission through daily contact is less common. Since the hepatitis B virus does not pass through the digestive tract, you will not usually be infected with the hepatitis B virus if you eat something that a person with hepatitis B has eaten. However, when both the hepatitis B infected person and the hepatitis B virus hepatitis B person who eat the same food have broken mouth and bleeding, the possibility of transmission of hepatitis B virus through the blood cannot be ruled out, therefore, it is still necessary to pay a little attention to avoid infection with hepatitis B virus, and be careful not to puncture the mouth when eating food.
