Is hepatitis B contagious? Should I eat with separate dishes if my family or friends have hepatitis B? This is a question that many of our friends are concerned about when they go out to the clinic. First of all, hepatitis B is contagious, but the contagiousness is relatively weak, and the general diet and daily work contact will not transmit hepatitis B. Secondly, and most importantly, hepatitis B can be prevented through vaccination. Therefore, the way to prevent hepatitis B is not by separating dishes and avoidance (which is not necessary at all), but by timely vaccination against hepatitis B. After vaccination, it is recommended to check whether antibodies are produced, and if antibodies are not produced or disappear, continue vaccination or booster vaccination against hepatitis B in a timely manner.
