The hepatitis B virus can be transmitted to others. When in close contact with a person with hepatitis B, such as when eating together, because the saliva of a person with hepatitis B contains the virus, the virus can contaminate the food if a common spoon or chopsticks are not used. If you do not have protective antibodies against hepatitis B and you have ulcers in your mouth, inflammation, erosion or ulcers in the mucous membrane of the digestive tract, the virus may invade your body through the broken mucous membrane. If you share razors, eyebrow razors, etc. with a hepatitis B carrier, when there is a break in the skin, the virus in the blood can be infected with these tools and infect others. The hepatitis B virus can also be transmitted through sexual intercourse during the couple’s life. If the mother is a hepatitis B carrier, the virus may be transmitted to the child through the placenta. Drug use and sharing syringes can also transmit the hepatitis B virus.
