Having Hepatitis B antibodies using chopsticks from a person with Hepatitis B usually does not require Hepatitis B immunoglobulin. Hepatitis B is transmitted through mother-to-child, blood (including tiny wounds to the skin and mucous membranes) and sexual contact, but not through the respiratory and digestive tracts. Therefore, daily study, work or living contacts, such as working in the same office, shaking hands, hugging, living in the same dormitory, eating in the same restaurant and sharing toilets, which do not involve blood exposure, will not be infected by hepatitis B. Those who are accidentally exposed to hepatitis B virus can be treated as follows: gently squeeze around the wound to drain the blood from the wound, rinse the wound with 0.9% saline, and then treat it with disinfectant; test for HBV-DNA and HBsAg immediately, and repeat the test in 3-6 months; those who have been vaccinated against hepatitis B and/or are known to be positive for anti-HBs may be exempted from treatment. If those who have not received hepatitis B vaccine, or those who have received hepatitis B vaccine but the anti-HBs is <10mIU/mL or the level of anti-HBs is not known, they should be injected with hepatitis B immunoglobulin 200~400IU immediately, and at the same time, they should receive one injection of hepatitis B vaccine (20ug) at different sites, and the second and third injection of hepatitis B vaccine (20ug) should be received one month and six months later respectively. The vaccine will be given at 1 month and 6 months after the vaccination. When discomfort occurs, consult the doctor promptly and treat the disease actively to avoid delaying the disease.
