Is the work of hepatitis B carriers limited? (Sichuan)

First of all, there are two mistakes in your question: hepatitis B is a viral disease, not a bacterial disease, so you should say "carrier" instead of "carrier"; Hepatitis B is an infectious disease, not a genetic disease, so there is no genetic problem. You can go to the hospital for HBV-DNA test. If DNA is positive and liver function is normal, it can be called a drug carrier, which is what people usually call a healthy carrier. According to national regulations, there are generally no restrictions on entering enterprises and taking exams for civil servants and institutions, but they cannot engage in preschool education, customs, catering and other work.
