Hepatitis B virus can be transmitted through blood, mother-to-child transmission, sexual contact, broken skin and mucous membrane contact transmission and other ways to infect the human body and spread the disease, but the World Health Organization clearly pointed out that sharing tableware will not spread hepatitis B virus. China is a country with a high prevalence of hepatitis B. Mother-to-child transmission is the main way of transmission of hepatitis B in China, and sexual transmission and blood transmission are also the more common ways of transmission of hepatitis B. The hepatitis B virus may exist in the blood, semen, saliva and breast milk of hepatitis B patients, but the content of the hepatitis B virus is highest in blood and very low in saliva, in addition, there are substances that inhibit the hepatitis B virus in the gastrointestinal tract and other digestive tract, which can destroy the hepatitis B virus in the digestive system, so sharing tableware will not spread the hepatitis B virus and infect hepatitis B. However, it should be noted that if the hepatitis B virus is replicated at a high level in the body of the person with the same meal, and the infected person has a mouth ulcer or broken gums, the risk of spreading hepatitis B through saliva contamination of the common dishes will increase. However, there is no need to overly panic because hepatitis B vaccination is a reliable way to prevent hepatitis B. Hepatitis B vaccination stimulates the body to produce hepatitis B surface antibodies, which protects the body from being infected by the hepatitis B virus. Therefore, if one of your close contacts such as family members has hepatitis B, it is recommended to check the hepatitis B two-to-one half. If the hepatitis B surface antibody is positive, it indicates that you have developed immunity to the hepatitis B virus and the risk of infection is extremely low; if the hepatitis B surface antibody is negative, it is recommended to get the hepatitis B vaccine in time to prevent infection. In summary, sharing dishes and utensils with hepatitis B patients generally does not transmit the disease, but people at high risk of close contact with hepatitis B patients should receive hepatitis B vaccination in a timely manner to stimulate the production of protective antibodies in the body and prevent infection with the disease.
